Are Disc Brakes Ready For The Tour De France? Road Disc Brakes Vs. Rim Brakes | GCN Does Science

Published on July 17th 2015


In association with SRAM. We can have something that the pros can't. Disc brakes. Are they ready for the pro peloton? We descended the Col du Tourmalet to find out. Click here to subscribe to GCN: Disc brakes have many performance advantages. But, despite their existence and safe use for years on mountain bikes, they remain banned in professional road races. As everyday riders, we think that they are, without a doubt, the way forward. However, there are some valid concerns about discs; overheating on descents, causing extra damage in crashes, adding weight on climbs and allowing those riders with discs to descend far faster than those without. Are any of these concerns valid? Dan and Simon descended the Col du Tourmalet twice, and climbed it once, all in the name of 'GCN Does Science'.
