You've heard it all. "26-inch this" or "29er that," well KHS shoots for the hallowed middle ground with the SixFifty 656 XC. This 650b bike gives you the best of both worlds with the acceleration and quick handling of a 26er, plus the roll-over-it capability of 29ers. Along with the steamrolling capability of the bigger wheels, you get 120mm of X-Fusion travel front and rear, making your 656 fully capable on just about any trail out there. The specs are just as legit with SRAM 3x10 gearing rocking you along, WTB wheels that are light and strong, and Avid Elixir discs that stop you like they mean it. The geometry is dialed, too: slack for confident descending and XC-sharp for twisty singletrack and tight switchbacks. Stop compromising and go 650b.
