It's time for another bonus episode of Geek Warning.Typically, we keep these bonus episodes for subscribers and members of Escape Collective, however, this one is being left open to all as a teaser for the type of stuff you’re missing by not being a member. If you like this and want more, sign up here.  This episode is about gravel tire selection and trends in the thinking that bigger is better. It all came about through an Instagram post by former WorldTour pro-turned Gravel Pro Alex Howes, who had shared just how much he had been obsessing over tire selection for the 2024 edition of Unbound Gravel. And what makes this conversation all the more interesting is that Howes isn’t sponsored by a single tire brand, but rather an online retailer that sells all the brands - biketiresdirect.Dave Rome and Howes cover a lot of ground in this one, including chatting slicks versus treads, picking the biggest volume possible, inserts or not, what to carry on a self-supported race like Unbound, and why white bar tape.If you don’t care about why, where, when, or how, and assuming the weather holds, Howes plans to race on Vittoria Terreno Zero tyres, in a 50 mm width up front and a 47 mm rear with inserts. He expects to start the day with approximately 19 psi in the front, and 24 psi rear. Still, if you find these details interesting, you’ll surely appreciate the conversation. Enjoy!
