October will be here before you know it and with it, comes Grinduro, a different kind of bike race. After my pre-ride photoshoot, one thing became evident: the best rig for this race is a cross bike. Don’t even try to ride a road bike, because you’ll be walking and if you ride a MTB, you might clock in a better time on the descents, but there’s a 25 mile climb.

When Giro announced the Grinduro, Santa Cruz framebuilder John Caletti of Caletti Cycles began working on a cyclocross bike for the event. With bent seat stays, clearances for a 40mm tire, disc brakes and no-rattle housing, this bike is the ideal weapon for a day filled with Sierra Nevada gravel and crag.

My favorite detail on this frame in particular however is the Geoff McFetridge artwork. The evil mountain awaits and Grinduro is coming… Best get your rig ready.
