Ro-Deux-No build notes New Bike Day

[Bill Lindsay]

I went to Riv HQ and picked up my 58cm Complete RoadUno.  I picked up the bike in the box to do the build myself.  I also splurged on an extra 250mm length Nitto S83 seat post.  

I did pretty much the whole build this afternoon, except I neglected to secure a chain.  I thought I had plenty of chain-stock on hand, but it turns out I only had 10sp chains, which I'm not prepared to deploy just yet.  

The setup was straightforward, but I did completely disassemble everything that was pre-assembled in the complete.  The frame set is not light: 5.83 pounds for the 58cm frame with headset cups, 2.18 pounds for the fork with enormously long steerer.  The new svelte Silver 3 cranks are roughly 25% lighter than the Silver 1 cranks.  

Thread chasing was necessary on the RD hanger, but it was aligned perfectly.  Most but not all of the H2O bolt and fender bolt bosses were already chased.  It was all straightforward prep for a mechanic.  There was no BB cable guide included, but I had those on-hand.  I installed a Shimano CX70 front der and a White Industries DOS ENO 16/19 freewheel.  I installed a Suntour Sprint down tube shifter on the shifter boss, with my own custom machined stop that causes it to sit proud of the down tube in the small-ring position.  

With the faceplater stem pretty much slammed, and the saddle at my height, I'm happy at the silhouette of the bike.  I'm eager to get a chain on it and start riding it.

Wow Bill - first happy customer this side of the ocean?

Guess that means mine will be shipping shortly, too…

Exciting times!

The little tweaks you’ve made so far to the build are all excellent. And I agree, the stance/silhouette looks ideal as it is.

Can I ask how tall you are?

Curious how exactly the same size (58) is gonna feel and fit when I get my hands on it!

I'm 5'10". My Saddle Height is 75.5cm, so I think that makes me a 86cm PBH guy.

[Richard Rose]

Bill, 5’10”? That surprised me. I’ve not ordered a Roaduno but thought if I did it would be a 54. I am 5’10” also but use a 72-73 saddle height. Perhaps your legs are longer than mine or maybe it’s my preferred mid-foot flat pedal position which tends to lower the saddle. Bike looks great!

Nice! and your shop is quite the Aladdin's cave as well.Not that it's disorganized but I could see how you'd lose track of your chain inventory

[DavidP]

Looks great, Bill. I think my favorite detail is the purple BB cable guide.

I like the 2x1(x2) setup and the custom stop on the DT shifter sounds and looks like a very nice ergonomic detail. My iBob cheap bike Univega has aero / top-mount DT shifters and I found that I liked having the shifter proud of the DT there. Looking forward to the Diablo summit.

Richard, I'm also a bit in between two sizes. At 5'11" with an 87cm PBH the 585mm ETT of the 54cm would work with either drops or swept back bars by changing stem length. If I wanted the bike to fit more like my 60cm Platypus though I'd want the 58cm for its 605mm ETT, and given the type of bike and my intended use that'd be my preference. I have my doubts on stand over but it seems I'd have slightly more clearance than Bill does.

[Bill Lindsay]

After a think last night I plowed ahead this morning with the 2x7 configuration, which requires a 10speed chain, which I had on-hand.  Turns out a single chain was long enough, which was a pleasant surprise.  It's all done and I rode it around the block.  It's new bike day.  I've added a bunch of photos to the Flickr album:

https://flickr.com/photos/45758191@N04/albums/72177720319657823/

here's the whole bike in 2x7 configuration:

Seeing your Roaduno made me envious and excited in anticipation of mine shipping.

Dave, I think my saddle height of 72.5 - 3cm less than Bills - and looking at Bills pics puts me solidly in the 54.5 camp.:)

A+ as usual, Bill!

[Bill Lindsay]

Happy Birthday!  If yours is a "fancy" build I saw it in Mark's stand yesterday.  

I just finished applying more Eggplant Newbaums on the top tube (for handlebar bash protection) and the chainstay, for long-chain slap protection.  The drive side chainstay had no protection at all, since its "base configuration" is a single speed with no derailleur or tensioner.  I also installed the front rack, basket and dynamo lamp, so now it's really complete.

Nice build and appreciated your input (in another thread?) on the Uno vs Quickbeam, swept bars etc. Intriguing and compelling bike. 

Looking forward to your take in the coming days and weeks on the overall ride and use cases for this configuration Uno - and any modifications! 

Chris 

[Michael Connors]

Hi Bill. I am nervous about running a tap in the RD hanger.  How do you make sure that you are in the existing thread and not cutting a new one?

[Bill Lindsay]

Good initial instruction, good tools, and lots of practice.  That's my formula for developing that confidence and mechanics' instinct.  I think most procedures really sink in after you fail one or more times, but failing at this operation on a new frame would be a bummer.  If you are nervous, have a pro do it.  If you want the practice, find a pro that will oversee you doing it.  

BL in EC

[iamkeith]

Beautiful, Bill.  I suspect you'll be responsible for a number of new Roaduno sales in the near future, as people see your bike.

When you have time, would you mind sharing some close-up pictures of tire clearances at the chain stays, seat stay brake bridge bridge and fork crown areas?   You build too quickly.  What I've really been dying to know is how big of a tire can be fit WITHOUT caliper brakes installed.  (I've been half-heartedly toying with a couple of alternative brake ideas since the Roaduno project shifted from a canti-clem to a caliper-homer format.)  I dont expect you to disassmle or try different tires but, for anyone else reading this and getting ready to start their own build, I'd appreciate any insights if it's convenient.

[Patrick Moore]

+ 1 for having a pro do it, and make sure it's a pro. I had the French threads in a nice Pro 5 Vis crankset tapped for English pedals by a nearby bike shop. The head mechanic was eager but inexperienced and got the right threads cockeyed. I had a heckofatime getting compensation from the owner (recall standing around in the store for about an hour as the owner did her very best to ignore me, but I persisted).

[Bill Lindsay]

Keith 

What exactly are you after?  Are you looking to build a Roaduno fixed with zero brakes and need to know max fenderless tire size you can run on your fixie?  Are you plotting a cantilever conversion on a Roaduno?  Do you have a particular tire size that you must have, or is it just you need to know the absolute largest tire that will fit without fenders.  Have you asked Rivendell to do these measurements for you?  If you are in market to buy a frame and since they have lots of frames, maybe that's their job?

I will be taking some Garage Door photos for Will, so he can put my build in the Riv email newsletter.  At that time, I'll try to capture what you may be after.

I've got an Ana Purple RoadUno showing up tomorrow, Friday.  (first bike purchase from Rivendell...)

I'm temporarily on weight lifting restrictions (thanks, cataract!), so I've recruited my son to lend me a hand. Maybe I lend him a beer or something...

As far as going fixed, I saw that the RoadUno page (one of them, can't recall which) recommends against doing so, as the bottom bracket drop is relatively low (80mm drop?) .

Thanks for the early build pics and tips. -- and (just noticed)  3 x 6  in the Flickr pages?   I'm probably going to use a 2spd kick back hub (yes, they are heavy....) with a 3 ring set up.

Cheers.

[Bill Lindsay]

"and (just noticed)  3 x 6  in the Flickr pages?"

My RoadUno is 2x7.  It's the stock 38/26 in front, and 12-28 in back  

"I'm probably going to use a 2spd kick back hub (yes, they are heavy....) with a 3 ring set up."

How will that work?  If you run a 3-ring setup with a front derailleur you'll need a tensioner of some kind.  If you run a 2 speed kickback hub you'll need to NOT run a tensioner of any kind.  

Will it be a 2-speed kickback setup with no tensioner, and you can manually move the wheel to accommodate one of the three rings?  If you do that, then you need new rear brake setup for each wheel position.  Will it be front brake only?  

Have fun with it, whatever you do.

Hi Bill -

My S-A 2sp does not have a coaster bake. So:  Rim Brakes 4ever!  (both front and rear)

I'm using a Paul Melvinator (high zoot!). I read - either at the Paul Comp website or Rivendell - it can accommodate 20t difference for the chainrings.

How the tensioner interacts with the kick back mechanism will be a bit of a SheldonBrown style experiment. I get your point - there's going to be some kind of finickiness between the chain tensioner and the force to shift when back pedaling. 

I'll have to start a thread on if it works or not. Maybe grab different deraiilleurs and set up a Design of Experiments!

I'm expecting fun - as soon as UPS gets it to me.... I missed the delivery this AM, as they moved the time up by more than 2 hours. :|

Mark V.

[Bill Lindsay]

I like the experiment a LOT, for three big reasons:  

1. "nobody" has done it before.

2. virtually everybody has never tried it.  

3. A good number of know it alls will tell you it's not possible, and they don't know from experience (see #2)

Have fun with it.  All "findings" are valuable.

Short of a contextual reply from you I added a few shots just for you in my "photo-shoot" this morning.  Here they are:

1. Chainstay shot: https://flickr.com/photos/45758191@N04/53942718939/in/album-72177720319657823

2. Rear Brake area shot: https://flickr.com/photos/45758191@N04/53942634628/in/album-72177720319657823/

3. Front Brake area shot: https://flickr.com/photos/45758191@N04/53942842180/in/album-72177720319657823/

Pictured are true 36.5mm tires on 25mm rims (outside width).  The model is Gravel King SK 700x35.  There are some notes in the photos on Flickr.  

Without knowing from you, my guess is that you are brainstorming getting cantilever posts installed on a RoadUno and want to know whether "tire X" will work.  I've got lots of mountain bike tires, the narrowest of which is probably about 55mm.  I'm 98% certain that a 55mm 29er tire will not work.  I also have Supple Vitesse 700x48 tires.  I'm 85% sure that would clear.  If you need (need!) me to pull the brake calipers and install the 700x48s onto a representative wheel set, and photograph that configuration for you, then let me know.

Bill, 

Short answer is that I was toying with the idea of an IGH drivetrain and drum brakes front and rear.  Not really using the frame the way it's intended - with torque arms attaching to a chainstay and fork leg, so not sure its appropriate to ask Riv to comment on.  I might be willing to assume the risk myself if it gets that far, though.  Target tire size for me is around 2.3 - 2.5 inches, in a slick or semi-slick "balloon" tread.

Longer answer is that I was initially excited about the Roaduno project when it was going to be like a Clem.   My family has a condo in Florida that I occasionally spend time at.  I don't really like it there, but would enjoy it much more if I kept a bike on hand so that I'm free to explore, and less dependent on the schedules of others.  Past rental experiences have been frustrating.  (It blows my mind how many crappy bikes exist.)  A 3-speed sturmey archer hub would be all the gearing I'd ever need in flatlands, and would be ideal from a maintenance standpoint, with all the sand and humidity and salt air.  But I absolutely would require a big baloon-like tire for floatation in the sand and boggy areas, and on poorly-maintained pavement.   Most of the streets are a death trap for cyclists (no shoulders, rednecks, elderly drivers, drunk college kids, overcrowded traffic), but there are rails-to-trails and informal wooded trails leading everywhere.   It occurred to me that, if I could fit the tire I want, drum brakes might be a pretty good idea for the same maintenance reasons.  Basically, an alternative to the awful beach cruisers and "fitness" bikes that are so prevalent down there.

[iamkeith]

Oops.  I responded to your first message before seeing your followup.  Thanks for the pics!

Coincidentally, I did find some clamp-on brake bosses for cantilever brakes at one point (like modern moots-mounts), so you weren't far off.  I can't seem to find them again at the moment, though.

[Bill Lindsay]

OK, interesting build concept.  I can state with certainty that a 2.5" tire won't fit in there.  It's definitely a Rivendell version of a Road Bike, and definitely not a sand bike.  It's an Appaloosa fork crown, so I imagine if you surveyed Appaloosa owners "what's the absolutely biggest tire without fenders" that would get you a few data points.  

BL in EC

[iamkeith]

Yea, I think I'm SOL.  Although the new appaloosa is said to take 2.5 - but that might include longer fork legs in the equation.

Just for the sake of converation completeness - or anybody else who might want to experiment  - here are the clamp-on brake bosses I mentioned:

[Eric Daume]

I think I would try this experiment with a really cheap rear derailleur from the co-op, not a Paul Melvin. But that's just me.

Hi Eric - I was planning on a 3x1 set up from the get go. I already ordered/received the 44t ring, the DT shifter, the Melvinator. I ordered up the RoadUno complete, so going 3x...2IGH (?) will just be a wheel swap from the stock wheel after I set up the 3x1.  First bunch of rides will be 1x1, since it's my understanding that's how I'm getting it.

Not sure if I need a BB swap to go to the 3 ring circus... crankset. I think I got a few BB rolling around the parts bin.

Hopefully photos tomorrow!

mark v.

[Bill Lindsay]

"Not sure if I need a BB swap to go to the 3 ring"

The "big ring" position is occupied by a guard, so you won't need a different BB.  Just pull the guard and put on your big ring in its place.

[Patrick Moore]

SA and someone else make or used recently to make 2 sp kickbacks without the coaster brakes which should work fine with derailleurs/tensioners. Quick Google just now shows only the SA SC2; a few years ago SA or/and someone else made a non-coaster-brake 2 sp kickback hub but I can't find any. Does anyone know the summer 2024 offerings?

I've thought of getting one, only I'd want one with H = direct but the only recent ones I've heard of were Bendix repros to be made in India and those seem to have evaporated. Again, does anyone know?

I'd use one with a pushbike.

The Bendix repo project was done (or at least completed) by SOMA under the "Eagle" name.  I've never been able to search for or find anything on SOMA's websites.  Maybe others can.  There appear to be parts available, but I can't find listings for the complete hub, whether discontinued or otherwise.

[Mark V]

hi Patrick - SRAM used to make a 2 speed AUTOMATICKS or AUTOMATIX. I'm uncertain if it automatically shifted above a certain RPM, or if the rider had to kick back a 1/4 rotation like the S-A. I think it was bigger and heavier than the S-A.

I bought my S-A off eBay a few years ago and I've been using on a Miyata OneThousand. I think I had a really hard time finding one without a coaster brake. The only one I could find was a bike shop in Canada with a NOS anodized blue.  (should look good with the Ana purple!)   I'm decommissioning the Miyata up size the frame and get a Rivendell. Finally.

Will asked for a curated photo-shoot this morning.  Of course I was happy to oblige.  Will indicated it was Grant who was concerned that others would demand that Riv replicate the Lindsay treatment, which is why Will put in the language that Riv can't replicate my build.

Unboxed and assembled enough for a Boss-Lady Permitted quick spin down the street and back.

I'm off my cataract-surgery restrictions later this week and get in a proper ride. I'll get the bars wrapped pretty soon. I need to make sure I like the brake levers where they are.

(I'm guessing I can't start my own "Iterations on Purple RoadUno" thread until I hit some time limit or number of posts. I'm not finding a "start a conversation" button anywhere. I'm new to the Googles Groups.)

[Patrick Moore]

Lol. When I ordered my first road custom in late 1994 I asked Grant to build me a road bike like my '92 XO-1 but "better." (He said, "Oh, it'll be better.")

He used the AR as a basic template tho' with road tubing and lugs, so it was 54 cm c-c (again, I'm 60 c-c for a level tt fistful road bike). I told him teasingly that I was going to broadcast this -- even then he was known for proselytizing about big frames -- and he said, "Don't you dare."

[Bill Lindsay]

You've told that story a hundred times, and I still don't comprehend what the "this" is that you were threatening to broadcast but that Grant did not want you to broadcast.  

Bill Lindsay

El Cerrito, CA

[Bill Lindsay]

What was it that Patrick Moore teasingly threatened to broadcast that Grant did not want broadcast?

A. That Grant would design a 54cm frame for an adult human that thinks they need a 60cm frame?

B. That Grant would allow "road" tubing to be used in an all-rounder clone?

C. That Grant would charge for a custom what was actually just an All-Rounder and not a new design?

D. Some other thing?

Bill Lindsay

El Cerrito, CA

[Edwin W]

A (ish) That while Grant was proselytizing that everyone has been undersized and should be on bigger sizes, for this guy who actually has embraced that big frame idea and small bit of seat post showing for a long time Grant is actually going to be DOWN sizing him to a 54.

Edwin

[Bill Lindsay]

That's only the case if one deliberately misrepresents the size of bicycles in the context of sloping top tubes.  Are you speculating that Patrick Moore was teasingly threatening to broadcast to the world "Grant insists that I ride a bike 6cm smaller than what I asked for!"?  If Patrick Moore did that, it would be a deliberate misrepresentation.  I guess if somebody threatened Grant "I'm going to deliberately misrepresent your bicycle designs to the public" then it would be perfectly natural for Grant to respond "Don't you dare".

Exactly! The years long mystery has been solved....

[Nick A.]

In an attempt to bring this back to the original build talk-

Mr. Lindsay, I'm loving your build and hope it serves you well. Brilliant move on the seatpost mounted RD shifter.

In light of a few posts mentioning chain tensioners, I'd like to add to the group saying "use an old derailleur". I used a Shimano RX-100.  To hold it in place, I cut an old spoke down and it's been working great.

Nick, falls church va

[Bill Lindsay]

An old derailleur has a lot of things going for it.  Just note that the drive side chainstay is totally unprotected.  That's why I wrapped it in Newbaums.  A purpose built tensioner tends to have a stronger spring, and a clutch RD would also have slap-preventing features.  It's a road bike, and that's why I've chosen a rear derailleur and good chainstay slap protection.  

BL in EC

[Jeff B]

Very nicely done Bill. Since reading Will's email a while back about potentially making the bike a 5 speed, I was thinking I would take on that task. Now I might not have to, ha.

My thought was that I could get a narrower Q-factor and a small range of useable gears. Almost like a classic randonneur bike. Although it is a Rivendell so it would be a little heavier than a spry classic rando.

Jeff, Woodland, Ca

[Igor]

I still am interested in purchasing one of these myself. PBH of 83. I do not like the aesthetics of the 51 frame nor would I want 650B. Seems like a 54.5 would be more than fine..

[Bill Lindsay]

I had a few self-imposed procedural responsibilities in my stable that delayed my first ride on my 7of9with10on5 RoadUno.  I had planned on doing my September Diablo Summit, but stayed up a little late last night and slept in a little long this morning.  So instead I did my very standard Grizzly Peak route.  Executive summary: 23 miles, 2500 feet of climbing, splendid bike.  Zero tweaks needed or planned.  Perfect weather.  

tl/dr

Even though the bike has my 7of9with10on5 drivetrain, I decided to use it as its core design intended, as a two-speed.  I left the chain on the 18 cog in back and didn't touch my seat tube mounted Rear shifter.  On the 23 mile ride I shifted exactly twice.  I started in "low" (26x18) and road out to the of Grizzly Peak.  One roadie passed me on the climb.  He was probably 30 pounds lighter than me and he was on a ~$10k Parlee.  He passed me, but he had to work to do it.  At the top of Grizzly I stopped to take a photo:

https://flickr.com/photos/45758191@N04/53964112524/in/album-72177720319657823

I left it in "low" as I coasted down the steep descent to Fish Ranch Road (max speed 32.2mph). Then I finished the second climb to the end of Grizzly Peak.  When I turned right onto Skyline/Old Tunnel, I shifted into "high" (38x18) and descended into Berkeley.  I stopped at Domingo Peet's and waited in the long line at Fournee Bakery.  There were lots of students out along the high-side of the UC Berkeley campus.  I think it's rush weekend for the greek organizations.  I continued to North Berkeley and shifted back into "low" to climb up Arlington Ave to home.  

The bike was a delight.  It's definitely an upright road bike, and it's exceedingly easy to ride.  I rode gloveless and the texture of my Vans grips and the roughness of shellacked Newbaums on the forward curves of the stock Choco bars make me think I'll probably run thin gloves In the future.  My 700x35 Gravel Kings were kind of skinny for the lousy pavement on the Old Tunnel Road descent.  Maybe I'll swap on the 700x43s that are on the stock wheels, or maybe I'll just swap over to the stock wheels wholesale.  

There are some loud complainers lamenting what the RoadUno became, because I think they wanted something more like a single speed Hunqapillar.  My enthusiasm for this bike was based on the idea that there's never been a bike quite like this, and I was eager to just let it be what it is and enjoy it for that.  I'm definitely all-in on that idea now.  With its long wheelbase and comparatively slack head angle it is indeed very smooth and stable as a road bike.  With a nice long front center, there's not even a threat of TCO.  I think this is going to make a really good S24O and touring bike.  

Also of note, it was new shoes day.  I haven't been riding flats much, and so I don't have a proper set of Adidas Sambas or the equivalent.  My wife didn't like the colors that Zappos had for Sambas, so we substituted Puma Palermos.  I liked them very much for the first ride out.  Pics prove that:

https://flickr.com/photos/45758191@N04/53964034033/in/album-72177720316423417

I'm super pleased with my new build and look forward to establishing its place in my stable.

hi Bill

I see you're using a NITTO S83 seatpost.

Any issues with the post slipping? Or do you 'feel' you're cranking on the seat binder bolt much more than the Rivendell recommended 10N-m ?

I'm asking as my stock-build Kalloy post slips. I don't know the amount of torque I'm applying to the seat binder bolt, but I'm certain I'm apply much more than the 10N-m. I've added a bit of carbon paste to to the seattube. Still slipped a bit.

I've gone a head and ordered a NITTO S65. In the past I've had something very similar to the stock-build (single clamp) Kalloy before and I'm not a fan of of how the seat-rail clamp mates up with the top of the post.

I need to post some updates to my thread. I did an 80 miler to Detroit yesterday, and a shorter dirt road ride today.

Thanks.

Mark

I am having no issues with the seat post slipping.

Mark,

Have you checked that the seatpost binder bolt is greased?

On my new Appaloosa, it wasn’t. I was having slipping issues until one day I tried to tighten it too hard and the bolt snapped. 

A new bolt, well-greased, and I never had a problem again. Didn’t need to tighten much either! All this with the stock kalloy seatpost.

>> busted <<

Hi Dan - no, I did not grease the binder bolt when I built up the bike. Rivendell's instructions even called that out - grease the binder bolt.

I'll do that today and give it a go. (i'll probably try to replace the bolt, as i probably went beyond the elastic stretch of the bolt....)

I joking said to my wife that I'm not used to new bikes, so I thought maybe everything was too clean.

Also - here at work - when I've dealt with fasteners we don't grease them. The allowed finishing / plating probably has some lubricating properties in a more controlled fashion.

Thanks for the input / feedback / reminder / dope slap!

Happy Trails

Just to close the loop, when I said in my Original Post that I disassembled 100% of the stuff that was assembled, the purpose of that step was to grease everything that needs grease, including the seat post bolt.  The most important place for grease is between the head of the bolt and the lug itself.  On the threads is nice also.  Grease up that bolt, so you can easily snug it up.

Man, you all jinxed me. I’ve not experienced post slippage on either of my two Riv’s. Or so I thought. All the talk of greasing binder bolts caused me to double check. On my Clem the post had actually slipped incrementally over time. It was about 2cm low. The bolt was greased but I made sure it was more thorough on reassembly. My Gus was similarly greased but I cleaned / regreased anyway. Snugged it up nicely with a “T” handle wrench & went for a beautiful 12 mile singletrack ride. It was so good and so beautiful I decided to do a second lap. I hit a bump (one of many) and you’d have thought I had a dropper post! I always carry a multi tool - but not today. I took a shortcut back to car & called it a day.

So.., what is the prevailing opinion on proper torque for these things? Mine was tight enough that cranking it any more would take some effort. I do not want to break a bolt as has happened to others here. Thanks in advance for your valued input.

I can't recall if I had started a thread or contributed to one when I had stripped the binder bolt on my Roadini, but as I recall, I went to a local nut/bolt store with the stripped one in hand.  I bought 4 new bolts with nuts (one set is in my seat bag ;-).  The original nut has some plastic or something within it (I can't recall the name?), and the store told me not to use that style (plus they didn't have it - so who knows which is better).  Anyhow, I used the new bolt and nut, blue thread lock on the bolt, and a bit of anti-seize compound on the post.  I put a bit of tape on the back of my post to check for slippage.  That was a few months ago and so far so good (and I've loosened the bolt once to drop the post a bit; a few weeks ago, and still good).

Forgot to mention, if I would have done what Bill mentions above, I likely would have never had the original issue.

[Richard Rose]

Still curious about a torque recommendation. Clearly mine is not tight enough.

Hi R.M. - apologies for being the Monkey's Paw.... or open side down horseshoe ...  or Eeyore's rain cloud...

I believe the seat binder bolts are 5mm. And 10N-m install torque is a good number

 -- here's chart giving guidelines for bolt size; fastener grade; and install torque.   https://www.engineeringtoolbox.com/metric-bolts-maximum-torque-d_2054.html

 -- I tried to read the grade stamped into my RoadUno bolt head, and I think it's a 12.9.  (my eyes ain't what they used to be and maybe never were)

If you think you might have additional slippage issue, you can also schmear carbon paste around the seat tube. The little carbone bits add some interference.

I've not noticed any more slipping after greasing the binder bolt and adding a bit of paste.   As mentioned previously, I have a GUNNAR CrossHairs that slipped when I used  a nicely polished NITTO post. Wish I had greased that binder bolt, but didn't think/know to do that. The paste helped, but eventually a cheap(er) Kalloy UNO worked better. I think it still had slight grooves from the machining processes.

Cheers!

Quick question 

Front derailleur clamp is 28.6 mm?

Got this one. Seems like it doesn’t quite fit
