Recreational Cyclocross and Gravelbiking This has to be the most physically intense sport ever invented. It's high speed bicycle racing on a short off road course or riding the off pavement rides on gravel like :The Dirty Kanza". We also have a dedicated Racing forum for the Cyclocross Hard Core Racers.

Challenge Gravel Grinder tires



Really excited to try these. Still recovering from last week's crash (not pretty), so it'll be another couple of days before I can start riding again.

Slower than I'd like, but it is what it is. Once the weather improves (snow yesterday and this morning), I'll resume riding to work.
