Are Heavier Riders Ever Faster, Mixing Carbon & Aluminium & TPU Tubes | GCN Tech Clinic

Welcome to the GCN Tech Clinic, where we tackle your most pressing bike maintenance and tech questions! In this episode, we use physics to explain why a heavier rider can be faster than a lighter rider on a flat time trial, and we settle the debate on which is more fuel efficient: a roof rack or a rear rack. Plus, we cover the real risks of using CO2 or electric pumps on TPE inner tubes.
