Will New UCI Rules Resurrect Rim Brakes? | GCN Tech Show Ep. 458

The UCI is reviewing the Lugano Charter and updating its technical rules, raising big questions about the future of bike design, weight limits, and whether lightweight rim brakes could make a comeback in pro racing. In Hot Tech, we dive into Shimano Dura-Ace discounts that point to a new release, Whaleroad’s 14-speed wireless electronic groupset, and Factor’s new ONE SP time trial setup. Plus, we introduce Magicshine as GCN Tech's official new lighting partner and break down your Comments of the Week!
