Ask Josh Anything #010

We've got a great batch of questions from you for Josh to contemplate this episode: Does the placebo effect apply to cycling clothes and shoes as well as to equipment? Since many rims are different widths in different places, where should we measure when applying the rule of 105? How much — if any — does a patched tube affect a bike's CRR? Are third-party ceramic bearings and oversized pulley wheels still relevant? How marginal of a gain do you get with a really nice hub? Is it faster to run a deeper wheel in the front than the rear? Josh will answer all of these — and more! — in this episode of Marginal Gains (Disclaimer: the answer almost always begins with "it depends.")
