Everyone wants free speed, but what are the simple changes you can make that cost almost nothing? We’re joined by cycling tech guru Josh Poertner, founder of Silca, to uncover the secrets to going faster for free.
In this video, Josh shares his expert insights on the easiest and most effective ways to save watts. From the power of a clean bike and wrinkle-free clothing to the surprising aerodynamic losses from flapping helmet straps, these are the marginal gains that really add up. We also discuss body hair, tyre pressure, and the one cheap upgrade that’s faster than most expensive ones.
