Prototype Bikes, Monster Gearing, and all the Unreleased Tech from Unbound Gravel

Unbound has become the epicenter for not just the latest gravel bike tech but also some of the most interesting equipment choices of the year. Alvin Holbrook spent the week in Emporia, Kansas, tracking the race and also tracking down prototype bikes from Orbea, Pinarello, and Specialized. He also found Lachlan Morton's Cannondale Topstone with its water-carrying Tailfin rack and custom front bag, some unreleased rubber from Pirelli, and what most of us would consider a reverse tire set-up that ended up winning the race.
