Remember that fancy, lightweight, and supple rear tire Bené René used on his Crust Bikes Lightning Bolt build? The one where he got in the freezing water in his skivvies? How could you forget? Well, the testing period is finished with the Cava tire, a file tread, fast-rolling, gravel tire with a plump profile of 47.99mm wide on a 650b diaphragm. Head on over to Ultradynamico to see the specs on the Cava and to pick up one or a pair.
