This week on the GCN Show, we dive into the "prohibitive" cost of cycling and investigate if the sport is actually cheaper than ever thanks to a booming second-hand market. We also explore a bizarre new scientific study suggesting that training in a hot tub could significantly boost your FTP. Plus, Dan recounts the moment he was overtaken by a World Champion while riding flat-out, and we take a look at Shimano’s latest "self-tightening" shoe patent.
