A lot of the Old Duffers might have started out as ex-roadies, but just as many are former expert level cross country racers from back in the day.
When you drill down a bit there’s not much difference between roadies and CX racers really. While most of us are happy to hit the trails in baggy shorts and an enduro jersey, the CX race heads will only be seen on their bike in lycra.
Thankfully, they’re not so obsessed with replica team kit. However, strange as it may seem, they have some odd ideas about what gear to use. Serious cross country racers were late to adopt suspension and disc brakes because most of them were convinced that performance increase offered was cancelled out by the weight gain.
They also have slightly weird fashion foibles too; they never, ever use helmet peaks and they do the roadie leg shaving thing.
