Brakes With No Power, Easier Gears, What Tyres Will Fit My Rims | GCN Tech Clinic

This week, Alex and Ollie are solving your most complex bike tech problems. We're tackling everything from a retro build with dangerously weak rim brakes to finding the absolute minimum rim width for your 30mm tyres.

Plus, we dive into some huge debates: Will riding a heavy mountain bike actually make you a better cyclist than riding your gravel bike? And we investigate the great chain wax conspiracy after a viewer's local bike shop advised AGAINST it in hot, dusty conditions. Are they giving good advice, or is there a conspiracy afoot to sell more chains?!
