Faulty Mechanical Shifting, 32-Inch Gravel Wheels, and Tubeless Tyre Hacks | GCN Tech Clinic

Welcome back to the GCN Tech Clinic, where we tackle your toughest bike maintenance and tech questions! This week, Ollie and Alex discuss whether you should wax your chain for a multi-day Alpine tour, the feasibility of 32-inch wheels on a gravel bike, and if sealant really works inside TPU tubes. If you have a question for a future episode, be sure to leave it in the comments using the hashtag #ASKGCNTECH.
