This is our 27.5" (650B) geared bike. After years of middling about in no-man’s land, the 27.5 deal has taken off big time. More fork and tire options has made this wheel size a less scary proposition. When we rode the first Option B we built back in 2008 we knew it could be a "thing", and now it is. If you like a little more flickability than a 29r allows and wouldn’t be caught dead on a 26” bike, this is your ride.
Most 1x, 2x, and 3x set-ups, but depends on chainstay length and tire size on your specific bike
