Parts for the Ridley

[Tom Kunich]

Over the next two weeks the Di2 components for the Ridley will be coming in. I got the front derailleur today. I went down into the garage and dug out the ProLite deep aluminum wheels ready to install the tubeless Vittoria tires on when they come in. I would have bought the Rubino Pros if they had been available but they weren't so I got the Corsa's. A little worse wear but a better grip on the road.

Tubeless simply because I'm going for lighter weight. But now that I watch the road closer for broken bottles, the small punctures do seal themselves.

There were several forks that I would have preferred but I settled for a new Pinarello fork. Funny thing is that the Pinarello fork doesn't break but the Specialized SL6 Tarmac that tapers out to 1 1/2" does. One of the major changes to the latest Specialized was to make the steering tube stouter.

While my Colnago C50 was not a light carbon bike it felt as solid as a rock and was one of the better riding bikes I had. I have no intentions of riding the Ridley to destruction so it will mainly be used in the hard climbing rides like Mt Hamilton (4,000 feet in 7 miles) and this time I will be sure to carry some power bars. Running out of nutrition makes what should have been a nice ride into a slog.

Didn’t the frame came with a fork? Modern frames come as a frameset today. This includes a fork, headset and often a seatpost. This is what you get if you want a Canyon Aeroad frame instead of a complete bike:

There's also the issue of the fork being compatible with the frame. Tom mentioned that this model has cable routing specific to electronic shifting, so it must be relatively new (2020 or later according to the Ridley website). If that's the case, it may be designed for their own fork dimensions, iow a Pinarello fork might throw off the intended geometry, or even not fit at all, but I could be wrong.

Popcorn, indeed!

[Tom Kunich]

Well, most of the frames being sold on Ebay have forks, but a surprisingly high percentage don't have forks. In some cases I suspect that it is because the carbon fiber fork was showing signs of breaking. In others, like the Ridley, to buy the stock fork would triple the price I paid. A 3T fork would cost $400. The latest Specialized Tarmac is an "improvement" over last year's because the forks don't break.

They are making forks with all sorts of weird size steering tubes so it is difficult to find the size your new frame takes. This makes for special forks and headsets for new carbon fiber bikes.

[AMuzi]

Not clear to me at all.

With same tire on same wheel, Michelin tube 65g and Torelli
or Ritchey rim liner 15g vs heavier bolt-in valve, heavier
tubeless rim liner and a couple ounces of latex (in Chalo
Cholina's colorful description, 'frog snot').

If you prefer tubeless, ride them but for road wheels
'tubeless for lighter weight' is probably not logical.

In that case I would not trust the frame because offering a frame without a fork is suspicious.

Well most weight saving aren’t bar I guess bragging rights, though inner
tubes unless one wants to go exotic ie thermoplastic will be heavier than
the sealant and valve, tubes are 125g valves are 20 something sealant 30/45
plus possibly slightly more heavy tape either way few grams.

Roger Merriman

[Lou Holtman]

If you want light weight you don’t put in 125 gr tubes. Don’t you have to renew that ‘frog snot’ from time to time? Were does the old snot go? Does it evaporate? You simply don’t put tubeless tires on and go to all that trouble for the weight savings. There is no weight saving.

There are applications for which tubeless has distinct
advantages.

Saving weight on road wheels is not one of them.

[Tom Kunich]

I just had to renew the sealant. Don't ask me where the initial sealant went because it wasn't in the tire. And it didn't leak out around the tire through imperfections in the rim.

[Tom Kunich]

I probably have to agree with you. Silca implies that a tire with a latex tube and a tubeless tire weigh about the same.

[Roger Meriman]

You do need to remove and replace the sealant yes.

For absolute lightest thermoplastic tubes are where it’s at which are very
light and expensive and they will work out at about the same weight as
sealant and valve. Possibly slightly lighter, depending on amount of
sealant. But slower rolling resistance apparently on the drum.

Latex though the only tubes able to compete on drum tests with tubeless ie
slower but by so little but they do loose air, and expensive and yes
heavier than tubeless.

Same for lightweight butyl which are broadly in latex tube weights.

Essentially unless you want to use TPU tubeless is lighter though we are
talking what 20grams or so difference between lightweight tubes Butyl/Latex
so well into marginal gains for weight!

Roger Merriman

[Tom Kunich]

The big advantage of tubeless is they don't get pinch flats and if you've ever been 20 miles from home and gotten a pinch flat and used your last tube and CO2 you know how worried you can get about pinch flats.

[Roger Meriman]

Can’t say on the road had many pinch flats, for road I’d probably go tubes
though depends on the type of riding, ie Sunday best club runs tubes all
day.

Gritty lanes mid winter? Tubeless sounds more appealing or rather fixing a
puncture in the falling light in the rain in a wet gritty lane doesn’t
appeal! Though I used to average 2 a year.

Roger Merriman

[Lou Holtman]

Can’t remember my last pinchflat, but hey everyone is welcome to go tubeless. As long as good clicher tires are available I won’t complain.

I used tubeless for quite some time and then since I wasn't getting flats I figured I didn't need them. And on new tires you don't. But it doesn't take much wear before tubeless makes more sense.

[Tom Kunich]

One week after I said that on here I rode over the RR tracks four blocks from here and pinch flatted both wheels. Good thing it was a short walk home.

[Tom Kunich]

We understand that you ride with saddlebags and multiple spare parts for every occasion. I don't and won't

[Roger Meriman]

For the gravel bike it’s really solved multiples punctures from well the
gravel!

On the road bikes, I used to run the tires mosty training type so stuff
like conti 4 seasons which would last maybe 2k on the rear and get maybe 2
punctures per year so generally not a huge problem.

The advantages seem less so for road, mind you I’ve not bothered for the
MTB as well tubes just work and I can’t be bothered with the maintenance,
where as with the Gravel bike which has had multiple independent punctures
before now on one ride it’s the easier system to live with.

Roger Merriman

[Frank Krygowski]

That's fine, do what you like. I wouldn't like to walk my bikes home, and I've never had to.

- Frank Krygowski

[Frank Krygowski]

Two good friends of ours recently got back from some sort of guided or supported
tour in New Mexico. I don't know which it was, but they were in Taos and Santa Fe,
either on the ride or while they were out there. I guess the riding was quite hot,
even in the mountains.

Anyway, I asked about flats and yes, they had many, from some sort of thorns. "Goat
heads?" "No, that was before we got to the goat heads."

I think if I were riding in territory with flat-causing thorns, I'd certainly consider some
sort of solution - sealant inside the tube, protective liners, whatever. But I think the
problem would have to be extreme before I'd go with tubeless .YMMV, of course.

- Frank Krygowski

[Tom Kunich]

The reason for that is that you either don't ride, or you always ride in a group that can supply back up support. Frank - you grow tiresome pretending that you're Mr. Bicycle. It is like your crap that you disagreed with Jobst. You kissed his ass and never did one thing other than mirror his statements as if they were yours. Though I hate to talk badly of the dead, especially since his son may be watching, but I am the only one here that actually knew him and he was very far from perfect. When he got so angry for being criticized that he publish what he thought was my address, it showed just what sort of jerk he really was. Essentially he was sic'ing his attack dogs on what turned out to be my mother. This also led to others of his ilk publishing the address of another Tom Kunich who also lived in San Leandro and his mother Mary Kunich who was no relation of any kind. You may not have approved of that but you said NOTHING.

How does it feel to be nothing more than a punk?

[Roger Meriman]

It depends personally the MTB tires are burly enough or at least the trail
type stuff, which is 1kg or so and armoured against sharp rocks and what
not. And well it’s works tubes that is, and easy enough to put a new tube
in. Though such tires do require a fair bit of man handling.

For the gravel bike you could fit heavyweight touring tires ie
marathon/Land Cruiser plus touring say or similar. But at that point your
making other compromises.

in terms of comfort ie running tubes the risk of a impact impacting a tube,
means you need higher pressures and such tires have a rather uncomfortable
wooden feel on tarmac let alone off road.

Grip though you’ll have mechanical grip possible more as Gravel tires tend
to the lower profile knobs. But wet surfaces will be fairly iffy as you the
compound is hard wearing rather than grippy plus the high pressures and
stiff sidewalls mean the tire will ping rather than conform to the
surfaces.

Rolling resistance is worse less so on tarmac but off road it’s heavy going
with such tires.

Some folks do make that choice, but you do miss out on the speed/grip that
gravel bikes have. For example one steep chalky climb if wet such tires (a
friend does this) will struggle with traction so ends up being a hike a
bike.

You tell us.....

[Tom Kunich]

I never had that feeling after grade school when I knocked a kid down for saying something insulting. Sure he never did that again, but I probably felt a lot worse than he did. Being trained by one of the local palookas put me in a position to know better than to take advantage of the ignorance of others. That includes you and I shouldn't have said that.

Your comments make me believe that you still race but why eludes me. Your comments about using a power meter were silly. If by this time you can't judge your power output you should just call it quits and go home. And I'm having trouble understanding why you would still be racing. Is it because it is something you like to do despite being unable to even see the 2nd group? Again that isn't an insult. You've told us what bikes and groups you have and you're simply not in the running. If you race it is because you like to race and not because you like to win.

I can't criticize that since I don't even like the idea of racing and I don['t like people behind me pouring it on so that they can pass me and then collapse.

Because it's fun.

Really? How so? I've realized some significant gains from my training programs using a power meter....that's silly?

Power meters keep your RPE honest and ensure you have usable metrics. RPE isn't reliable (not even to the pros, which is why they use power meters) I'm not surprised you don't get that.

> And I'm having trouble understanding why you would still be racing.

I'm not surprised. So much escapes your grasp.

> Is it because it is something you like to do despite being unable to even see the 2nd group? Again that isn't an insult.

I wouldn't take it as one. There is a certain amount of satisfaction when I can look around from the lead group and not see the second group.

> You've told us what bikes and groups you have and you're simply not in the running.

Refresh my memory...what bikes do I ride that aren't race-worthy?

Winning is fun, but it isn't why I race.

> I can't criticize that since I don't even like the idea of racing and I don['t like people behind me pouring it on so that they can pass me and then collapse.

You can't criticize it....yet you do....

Are you man enough to meet me face to face? I can show you how badly I am disabled from those "meds". Did you use that because you cannot spell "medicine"?

Yup.

OOOOO!!!! I SCARED!!!!!!

> Did you use that because you cannot spell "medicine"?

I can spell it better that you can spell "Functional Threshold Power".

You're obviously unfamiliar with USAC rules.

> you obviously hold contempt for the entire world.

No, just you (and that pseudo-irish shit stain).

> You have told us the crap bikes you have.

Remind me again what bikes I've claimed I have that aren't race-worthy according the Great Tommy Kunich: Masterful Oracle of All Things (second request)?

What this really comes down to is that tommy is admitting "yes, I'm full of shit and cannot produce any evidence that FTP is "Full Time Power".

I'd be interested what you've deluded yourself into thinking RPE means in the context of exercise physiology - don't google it, just tell us (this ought to be good for a laugh).

[Tom Kunich]

"Functional Threshold Power (FTP), the maximum power you can hold for roughly 60 minutes." In other words FULL TIME POWER all dolled up so that full time engineers can talk about it in awe.

[funkma...@hotmail.com]

lol...so you admit I'm a fulltime engineer, and you aren't....

First off, I didn't ask you about FTP, I asked you about RPE.

Second, there is no "in other words" about it. "full time power" is not a phrase anyone uses, let alone being the "more commonly used" phrase (in your words). In other words, you're wrong.....again.

[Tom Kunich]

No real engineer has time to play tag on a news group so stop pretending that you're an engineer. You don't even know how much money engineers make

[funkma...@hotmail.com]

Aww...poor tommy's jealous that I have the skills to manage my job to allow some time on the internet - and that my company doesn't mind that IT do it. Too bad you never impressed you managers to such an extent that they gave you that latitude.

> You don't even know how much money engineers make

I know that I'm making more than the local average for my postion, and I know that a non degreed engineer wasn't making $250K 20+ years ago.

What this really comes down to is that tommy is admitting "I'm full of shit and can't produce any evidence that FTP means Full Time Power". Now we can also add RPE to the (very) long list of things tommy doesn't understand.

[Tom Kunich]

So that is what you call it!. Managing your job so that you can play on the Internet. I should have learned how to do that. But I seemed to always have jobs that took up all of my work hours plus overtime, plus getting there early in the morning to set everything up for the day.

If you're making more than the average engineer in your area, someone is not playing with a full deck and your employers are unlikely to remain in business in a non-Obama/Biden job market. No wonder you think that Obama and Biden are so wonderful.

[funkma...@hotmail.com]

My company has been around since 1936, with no signs of slowing down (we just missed profit-margin stretch goal for FY 22). And BTW - republican administrations are typically much more friendly to my industry. Considering we did as well though trump as we did though both Obama and Biden (marginal drop in sales/profit through the pandemic, I got kudos and a nice raise for managing component supply chain issues), this company isn't going anywhere for a long, long time, so you can shove your economic/political chicken-little forecasting firmly up your ass while wearing your tin-foil hat.

> No wonder you think that Obama and Biden are so wonderful.

I liked Obama, Biden, not so much. But considering the alternative of an ignorant arrogant narcissist completely devoid of any moral foundation, Biden was best choice.

[Tom Kunich]

Thanks for telling us what you're real job is. Not engineering.

Historically, the economy has performed much better during Democratic
administrations than Republican administrations. Economic growth, job
creation and industrial production all have done better under Democratic
presidents.

Also recall that both Obama and Clinton inherited an economy in trouble,
Clinton from Reagan/Bush and Obama from W. The recovery from the failed
policies of Reagan/Bush and W could only have occurred under a
Democratic administration. Trump was fortunate to inherit a very robust
economy from Obama. If Trump had not mismanaged the Covid pandemic so
terribly bad he would almost certainly have been re-elected.

[funkma...@hotmail.com]

So alternative component selection to replace unavailable parts - involving analysis of performance characteristics and engineering qualification testing isn't engineering? I guess that shows how much real engineering you've actually done. Tell us oh great one, how would you characterize the thermal junction rating of a semiconductor device to validate Intrinsic Safety performance?

What this really comes down to is that tommy is admitting "I'm full of shit and can't produce any evidence that FTP stands for Full Time Power".

Yes, I've read the charts and analysis which support that. It's obvious to anyone who isn't a right-wing partisan hack

I don't think so. There was a massive turnout against trump because he was an ignorant arrogant narcissist completely devoid of any moral foundation. I think most people feel the same way about Biden that I do. Not our first choice (or even my second), considering the alternative......

Biden was not my preferred choice either but it was clear that only a
moderate, experienced, Christian, Caucasian, Democrat could defeat
Trump. Biden was that person. Bernie would have been fine with me, but
he is too far left, and Jewish, so he would not have beaten Trump.

For this election I wish that a moral Republican like Adam Kinzinger
would switch parties and run as a Democrat. Former Senator Ben Sasse
would be a good Republican candidate, a lot better than Trump or De Santis.

But, Tommy has told us about his job interviewing AIDS suffers. You
know, "who did what to who" and "How long ago did this happen", and so
on. Wouldn't he be paid a quarter million for this highly technical
and dangerious job?

But lets face facts, Tommy is his own worst enemy. He tells a lie and
then forgets what he said and tells another lie that contradicts the
first lie. What he should do is buy a notebook and write down his lies
as he tells them to keep tract of what he says so he won't keep

I see that you see every possible division rather than any possible unification. Is that because you couldn't get a vote the second time around because everyone hated you?
