We are on the ground at Sea Otter chasing Marginal Gains. A top theme at this year's show is something we have been discussing in our episodes: the wider tire revolution. Older XC tires have found new life on gravel race bikes and tire makers are responding. We hear from two major players on the tire side of things. Plus Dylan Johnson weighs in on how widespread the wider tire movement has become at the pointy end of races.

We also wadedinto some new terrirotry: bike rack and bag maker Tailfin talks about its go-fast approach to bike packing. And finally, we met up with a one-of-a-kind company that has brought Marginal Gains...to leg shaving.
