How wide is too wide for road bike tires? We know that wider tires are faster, but how wide can you go until this stops being true? Hank and Alex are back with more GCN Does Science to test out three different tire widths: standard 26mm, chunky 35mm and super-size 50mm. How much does tire width really affect comfort, confidence, bike handling and speed?
