Orthos

[Andrew Joseph]

Bars slippage reports came in at an interesting point for me.

What was the consensus on getting them to stay put?

The Sam rebuild is almost there. Orthos will be angle down slightly more, bar tape and need longer dynamo wires for the Pass and Stow….

[Ryan Ogilvie]

My view is that the single bolt clamps just don’t have a sufficient clamping force to keep the Orthos from slipping. Even if you tighten it so it stays put, you’ve over-torqued the fastener which can lead to bad summer teeth (some’r her, some’r there). A four bolt plate should work, tho.

That is a gorgeous bike! I think the vast majority don't have issues with slipping. I wouldn't worry about it UNLESS you have an issue which may be partially riding style and habits...I think the main points from the other thread are to make sure your stem bolt is greased and you use adequate torque to prevent slip but also not so much torque that you over-tighten as it could ovalize the bar since it's thin. 

[Andrew Joseph]

Thank you! I’m glad you like my interpretation so far.  Will send the finished project…

Noted on the stem. Hopefully, it won’t be an issue.

Cheers,

Drew

My orthos slipped a lot. What I finally did was mount them in a 31.8 four bolt stem with a shim. Now they don’t move at all. Maybe worth a try.  Bill

[David Ross]

I’ve had good results with the Park anti slip gel, using a 26mm stem on my 90s mtb and also on another ATB I have that’s running a 31.8 with a shim. That’s good for general riding. However, if you’re going to ride really technical stuff and apply a lot of leverage to the bar ends, they’re going to slip in my experience. I have another set of Doom copies of an Albatross on my Gus with a 22.2 bmx stem and they do not slip, even when riding technical stuff. Another thing I’ve learned to do is to hold the area in front of the levers if I’m going to apply a lot of leverage to the bars.

[David Ross]

I’d also add that the guy who designed the Orthos uses a 25.4 single bolt stem on the Orthos even though they are 26mm. I think he actually designed them to work this way. Personally, I don’t know enough about engineering or metallurgy to know if this is a good or bad idea, so please don’t think I’m advising you to do this.

[Danny]

Great looking build!

[Mackenzy Albright]

Just to re-comment- because I like looking at this bike: in all honestly I haven't given much attention to Ortho bars in the past as I find them a bit overwhelming on most builds in terms of a visual focus as they are so large. In this case I feel as if they are made for the bike and absolutely perfect proportionally and fit the build to a T. Have you had a chance to take it for a ride? 

[Brent Knepper]

+1 on how nice that silverSammer looks! excellent monochrome skills

+1 also on orthos with a single-bolt 25.4 stem not slipping ◡̈ mine are on a 130 ITM stem, I bunnyhop up curbs and noodle around on rooty trails (although these bars noodle around on any surface) without a slip- no torque wrench just the usual 6mm allen key tightening amount I'd do on any nitto stem

-Brent in N(oodle)Y

[Andrew Joseph]

Thank you for the kind words everyone.

Yes, managed a short test ride this evening!  Initial thoughts…they offer a lot more control and compliance than they look like they would. 

I’ve really almost exclusively run drops for many years, but I must agree with Mackenzy.

I think (for me) these bars pair very well with the Sam.

Cheers,

Drew

[Wesley]

Love Ron's Orthos - looking to buy some if anyone has any laying around that they are willing to part with!

[Kim H.]

@Wesley,

Check Crust Classifieds

Kim Hetzel.

They just maybe still available...

[Davey Two Shoes]

I've got to say these are probably my favorite bars ever, I run them on my Tanglefoot Hardtack which is my bike for Singletrack or hanging with the little guy. I've tried maybe 5 other bars over the last year and always come back to Ron's. I'm tempted to try them on my Sam but I think I'd have issues with reach restrictions.

[Andrew Joseph]

For what it’s worth.  Bars are still holding!

[Armand Kizirian]

I absolutely love mine. As a 5'11" male with a built physique, I appreciate having adequate leverage on the bars when out of the saddle, but still find them to be incredibly comfortable when upright and relaxed. Allows lots of control and keeps my chest wide and open.

[Armand Kizirian]

Oh and a 25.4 nitto faceplater clamps mine no problem.

[Donzaemon]

When you say you have leverage out of the saddle, is it because you're grasping the curves in front of the levers/shifters?

[David Ross]

If you love crust orthos, you can have Doom make you a modified copy that will fit your Sam they can bump them forward 30mm or so. I have a scaled up version of an Albatross on one of my bikes and it’s fantastic. I was feeling indulgent with myself and I had them made in titanium. I have an exact steel replica of an Ortho on my Gus, but with that frame there aren’t any fit issues.

[Brian Turner]

It's worth noting for anyone wanting to test the general gist of Ron's Ortho bars without the price or hassle of tracking them down - I can say from experience that the widest Toscos sold by Rivendell (the 65cm, 38.1 version) are very, very similar to Ron's Ortho bars. Aside from the clamp diameter (you'd need a 38.1 faceplate stem), weight, and flex... but if you were looking to get a nearly identical riding position and width, Toscos would get you there.

I put Orthos on my Gus for a few months, but found them to be a bit too flexy for rougher trail riding. I swapped back to my Toscos after a few rides on mtn bike trails. I'm keeping them though, because I may use them on a future build.

[David Ross]

The flex is a real issue to consider. The Orthos are alloy and I’m not too keen on flexing aluminum because after a time, it will fail. The only issue with the Toscos is that the bars drop down in front of the brake levers, so I found the hand positions weren’t quite as useful. They’re fantastic bars otherwise and I much prefer a steel bar.

[Armand Kizirian]

Donzaemon, more specifically the width of the curves in front of the levers/shifters. I tried Billy bars before the Ortho's, which technically has the same two hand positions. I found them to be too narrow while climbing out of the saddle and did not stabilize my upper body enough to really put power down. This may be irrelevant if you don't have mountains to climb frequently, but I do.

[Ryan Frahm]

Armand, i agree! The width, the flare, all of it. I do hope to have a steel or Ti set bent up by Doom eventually, but I am loving this bar over any other swept bar I’ve tried. 

[Eric Marth]

Hello — I've been running my Orthos for over a year with a 26.0 Technomic, no slippage. 

I've long suspected what Brian Turner confirms: The widest Toscos are quite similar to the Orthos.

One more confirmation.  I actually just logged in to mention this, having forgotten to mention it the first time I read this thread.  The two bars are virtually identical in terms of grip position.  I posted several side-by-side images somewhere in the list, within the last year or so.  I'll see if I can find the thread when I have time.

 I have two of each, I love them so much.  FWIW, I have also slowly been transitioning most of my bikes to steel bars.  There are some things more important than weight, and there's no equivalent to a stiff, wide bar that doesn't flex away from you when you jump out of the saddle, and lets you throw your weight side to side for sprinting or climbing.  Now that the industry has FINALLY started offering wide-enough bars, the flex thing becomes more noticeable.   The extra peace of mind knowing steel is not going to fatigue like aluminum is nice, too.

In my mind, there's no question that the normal clamp diameter and graceful curves of the Ortho bars are better looking.  But the knurled 31.8 clamp area of the Toscos would solve your slipping issue once and for all.  WITH the benefits of being steel. 

[brendonoid]

Just another reiteration of previous posts, but I love my Orthos on my Clydesdale commuter that has been my main suburban steed since January. Held securely with a 25.4 alloy faceplater stem. Super comfy bars on an old Opafiets frame. Hard to get the bars up high enough on those things without the quill stem.

The flex of the bars makes me not want to use them for spicy riding though. Would go a Mothbar or Tosco as others have suggested.

[Davey Two Shoes]

I love the flex on the rough stuff, its why I keep returning to the Orthos

[Chris Halasz]

Orthos look nice, but may be too wide for me. 

Very happy with my 60cm Toscos. So pleased, in fact, that from here on out I only plan to ride bikes that can accommodate Ortho (or Losco) bars.
