UAE On Rim Brakes

Notices
Road Cycling “It 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.” -- Ernest Hemingway

Have fun riding your BSO buddy. You wait till starva hears what you've been up to.
The frame has a UCI seal on it so they approve.

Maybe I just need to drop a chain down the seatpost.

They went too far now. Why would they make their own equipment decisions without consulting the general public first? I'm having a hard time with this one.

I thought I remember seeing that even the carbon layup was specific to each rider. Don't ask me to back that up but I thought that was the case. In any event I really don't think its even remotely a challenge for these bikes being used in The Tour to made with discs at the minimum weight limit, regardless of manufacturer.

The bike ridden has to be sold to the public even if it is some months later that year. I did read one team had to resort to shallow al rims to make up the weight penalty. Sorry I don't remember which team and I'm out the door.

That sounds highly unlikely. They might well use a lighter, more exotic layup for their pro team bikes. But there is no reason why they would modify the layup for individual riders.

With tubulars it's fairly easy to reach the 6.8kg at UCI weighting rules (with pedals, bottle cages, transponder and Garmin mount) on a light disc brake bike. If the frame is heavy (as some aero ones are) or you are not running tubulars, it becomes more difficult and the weight savings become somewhat relevant.

I heard from a reliable source that the reason they switched to rim brakes was that they traded their disc brake rotors to another team for spare tubes. Apparently, supply chain issues are hitting the TdF pretty hard.

What I heard was that because of the steel shortage, their team food preparers were having a hard time getting blades for their meat cutting machines. They had to convert a lot of the disc rotors to cutting blades. They also had to get some of their beef out of Spain, so we might see a few failed drugs tests in the near future.

Well, that was dumb of them to trade for tubes. Don't they know that they're ~55% less likely to win a Le Tour stage with clinchers vs tubulars?

They didn't actually use the tubes -- they traded them for fancy watches.

THIS.

I started riding again last year due to the pandemic and my rim brake equiped bike promptly started to overheat and emit a burned rubber smell as I was descending at around 35-40 mph; I started losing confidence in my braking. I switched to a disc brake equipped bike and although it still overheats during fast descents (and does require some adjustments to reduce brake rub), there is no smell and I have more confidence in my braking power. During foggy/wet conditions, it's no contest.

With lighter bikes these days, the argument that rim brakes are lighter is not an argument, anymore. It's all about what you're used to and pros do not like change as stated previously.

Also, it seems pretty clear that the main reason they switched was so that they could tell the riders they were getting special climbing bikes that were definitely faster than their regular bikes.

But can it slow/stop without overheating or fading?

Brakes are overrated. All they do is slow you down when all you really want is to go faster.

would make sure you buy good disc brake wheel if you are causing brakes to heat up like that. Disc brakes require a very good spoke set up. As the force to stop is carried by the spokes. Rim brakes use the rim itself.

The whole move to disc brakes is money driven. Cheap for manufactures to make one style of bike than two. The cycling industry is so centralized on a few equipment markers now days compared to years ago. When there where many equipment group makers. It’s funny when people talk about bikes now days. Perrry much everyone is using Shimano. To the point that everyone is riding the same bike.

Agree. I wish there was more competition in the component arena: right now, there is the holy trinity of Shimano, Campy, and SRAM.

They both transfer the stopping force via the spokes.

One more than the other. Considerably more.

That must have been a very long time ago. I've been cycling for 40 something years and it's always been Shimano vs Campag in that time (except for Suntour on cheaper setups). SRAM wasn't even on the scene in road bikes back then and only had their grip-shift. What others did I miss?
