Erik Zabel: Disc brakes can be the difference between winning and losing

Disc brakes can make the difference between winning and losing, according to Erik Zabel, and the German is doing his best to make sure that Katusha-Alpecin is on the winning side. Zabel joined the team as their performance manager over the winter, having previously worked with them as a sprint coach before he was suspended after he confessed to doping during his career.
