Wyman switches between vented and solid rotors depending on the course conditions
"We found that the braking performance is really greatly increased, and with the solid rotor there's almost no brake [pad] wear in a muddy race," he said. "It's unbelievable how it changes the longevity of your brake pads."
Despite what he sees as a huge performance advantage, Stefan Wyman admits that there's still little sign of a sea change when it comes to the European arena.
"In America, you have a lot of individuals [single-person teams], but the market in Europe, in terms of the racers, is driven by a few big, dominant teams," he said. "You're dealing with people that have been setting up 'cross bikes for 25 years and it's a big change. In Belgium, there's a big feeling that 'cross is traditional and it should be this, and it should be that. It's going to take a big change in attitude."
"There's also the misconception that there's a weight penalty with discs. This bike is 6.97kg [15.37lb] and that's not a weight penalty. It's less than 200g over the weight limit. There's absolutely no reason not to change over, apart from a lack of knowledge of how it works and the traditional elements of it, really."
