It's been several years since disc brakes emerged as a viable way to slow down road bikes. It was roughly 2013 when we first saw the cycling industry begin to fully embrace the standard that's been the norm on mountain bike for years, with both bike makers and component giants SRAM and Shimano launching into the disc brake arena. Heck we've even been through one major disc brake recall. Yet, at the sport's highest level, there's still hesitation. A year ago we heard talk that disc brakes might be introduced into the pro peloton on a limited basis this year. But that's yet to materialize. So what's the hold up? And could disc brakes work in a race such as the Tour de France. Our friends at the Global Cycling Network investigate with some real world testing.
