UAE On Rim Brakes

Notices
Road Cycling ďIt is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.Ē -- Ernest Hemingway

UAE is the team in question.
They ride Colnago.
Is a Colnago disc bike like they ride 6.8kg?
I doubt it.

I canít bench 500lbs​​​​​ so it is clearly impossible. An example of willful ignorance.

I guess "willful ignorance" was the new phrase in day care today.

Why do you doubt it? Anything you can let us in on or are you just being contrary? The other manufacturers are getting their climbing bikes there. Why can't Colnago?

It just shows that disc brakes are not a guarantee of winning.

I didn't say it did. All I did was clarify the point behind another poster's message, which about sports people in general.

Ive said it many times but IMO pro cyclists are not the ones who need disc brakes, its us punters.

6.9kg for the rim brake version.

Colnago, like Pinarello are known for making good bikes but not light bikes.
A GCN review of the 2020 Colnago V3r (Davide Formolo's) rim brake bike was 6.9kg.
That is why I doubt it.

Cervelo R5 Disc is 1/2 pound more than the rim version in DA.

The V3R that UAE is riding was specifically developed to be light, unlike the C64. The disc frame only weighs 790 grams. That is pretty light for a company that doesn't make light bikes...

It is an accurate description of the behavior you are exhibiting.

You might want to read this:
https://cyclingtips.com/2019/07/how-...-change-wheel/

Twenty seconds from mechanic arrival to rider departure is a few seconds longer than the fastest rim brake wheel changes, particularly if we look back to the days when lawyer tabs were filed off. Back then, a very good mechanic could swap a wheel and push their rider off in less than ten seconds. But with lawyer tabs in place, the gap narrows considerably Ė in fact, a few mechanics have told me that a disc wheel change with an impact driver can be faster.

In the end, thanks to a bit of mechanization, itís largely a wash. Thereís more time to be gained or lost in the skill of the mechanic than in the type of axle and brake used by the rider.

Charming response. Which one is it by the way, change the wheel with a drill or bike swap?

The bikes that they ride in the tour are rarely exactly the same stock as the OEM versions of the bikes sold retail. For one thing, the wheels are almost always different.

So did you start this obvious troll thread to criticize and make snarky comments to anyone who does not agree? Perhaps go on your usual Sunday group ride which will have a majority of disc brake riders and start picking arguments with them.

Contributing nothing to the post again I see.

Yawn. This is like when a three-year-old learns to say poop, and keeps repeating it at every opportunity.

In the 2019 Cycle Oregon, they had several riders with heat damaged carbon rims from one of the descents between Steamboat and Culp Creek Oregon.

Of course Cycle Oregon riders may use their brakes very differently than pro racers.

This is why I have carbon wheels with aluminum brake tracks. I am basically a chicken on descents and rise my brakes a lot.

It's easy to get under the UCI minimum on a ready to ride bike shaped object.
You can't really go around calling it a bike if it's not UCI compliant.

Have fun riding your BSO buddy. You wait till starva hears what you've been up to.

I think it is quite interesting. I noticed not all of the UAE team used rim brakes yesterday. Obviously Pogacar and some of the others did. But for whatever reason the team was split between rim and disc - personal rider preference or logistic limitations? Maybe their Colnago disc bike struggles to get down to min weight, or maybe they feel wheel changes are slightly quicker with their rim brake bike. Maybe both. But I very much doubt they chose rim brakes for their actual braking performance.

It was also quite interesting that they used disc brakes on the earlier wet mountain stages. I can only think they would do this if the braking performance was superior. Otherwise why not use lighter rim brakes for ALL the big mountain stages?

So what does this mean from an average rider's perspective? Not much other than high-end rim brakes are still pretty effective and super-light, but disc brakes work more consistently in a wider range of conditions. Changing wheels is trivially easy on both when every last second doesn't count. I personally prefer through axles for their easy self-alignment.
