I'm guessing that it's done more for the aero than braking advantages.

As someone who has crashed into the side of a car in the wet because my brakes didn't work, I hardly think there isn't a problem rim brakes in the wet.* Initial bite is important with emergency braking. You need to be able to decelerate instantly in an emergency, not wait for the front rim to dry first.RonK wrote:The most telling comments: "a new product to empty your wallet" and "a solution to a problem that doesn't exist".

Go back and read his post properly-Emergency Braking. You know, the Jeebers moment when every microsecond and centimetre counts. Maybe if Nobody and myself were mind readers we'd be able to foresee the event in time to scrub the rims dry.

That's one reason (other than unpredictable braking) why I swapped to disc first on the MTB. Got tired of wearing away my front rim in the wet.warthog1 wrote:I'm thinking of a front disc on my Azzurri commuter similar to what you are running Nobody. My reason is that the rim brakes are wearing the bejeezus out of my front rim. The wet rim picks up grit that ends up becoming embedded in the pads. The noise coming from the rim on one of my kangaroo populated steep descents during my commute sounds terrible. The rim is getting chewed up fast.
Discs are about $30. A steel one should last a long time. A new Avid one is ~1.82mm by my digital vernier calipers. Mine is down to ~1.74mm now with about a guestimate of 2/3 to 3/4 of the pads used. Although I haven't found a minimum spec, I'd probably replace at about 1.5mm for safety which may be after two sets of pads. That might end up being a total of 7 years or more for me.warthog1 wrote:Are discs a bit more durable or cheaper to replace if not?

However the main reasons to change for me would be the extra wet weather safety and not having to listen to my rims grinding away.

I think it's more like they can win or lose races by the tiniest of margins. They also live in a different world to us as they can go fast enough that aero makes a significant difference and cars don't suddenly pull out on them in a race.mrgolf wrote:As for the other brakes from the original post, its kind of scary to think that pros are being expected to ride something with poorer braking ability than what is possible from widely accepted industry standard brakes. The aero advantage must be immense!!!
