The Cobbled Classics are here, bringing some of the most brutal racing of the season, but why have the pros stopped using crazy custom tech and suspension for Paris-Roubaix? We dive into the science of tyre clearance, rolling resistance, and aerodynamics to explain why you probably won’t see 40mm tyres on the cobbles anytime soon. Plus, we check out a weird new graphite chain lube on Kickstarter, share some latest Zwift news, and rate your rides in the Bike Vault!
