"Racing blood, trail spirit"
"It's devilishly quick, accelerates in a way that makes it seem like my legs actually produce real power. It's stable, planted, and it tracks like it's supposed to. Endurance athletes will be able to remain seated over more terrain, saving precious energy over the long haul, while XC pinners will hook up better on steep technical climbs."Read more
"Super light and fast as hell"
"The new Top Fuel might not be a pure XC-race bike anymore, but it's still precise and very fast. Its new trail orientation makes it a great choice for a rider who wants a fast and light bike with most of the the efficiency of a cross-country race bike, but with bit more versatility and playfulness."Read more

Will my bike have a curved top tube?
Smaller frames (S) have a top tube that dips down as it approaches the seat tube. This design makes for a lower standover height, which is good for shorter riders because it allows them to straddle their bike more easily. Larger frames (M and up) have a straight top tube because taller riders with longer legs typically don’t have the same issues with standover height.
TwistLoc Dual Remote Lockout
TwistLoc simultaneously locks out front and rear shocks with a simple Grip Shift-like motion; and it leaves room for a dropper post lever.
Control Freak Cable Management
The lightest, quietest, most versatile cable management system allows any combination of shift, brake, lockout, and dropper post lines to be routed through the frame for clean looks and the ultimate custom setup.

Sizing & fit
The charts below show our recommended sizes based on height, but there are some other factors, like arm and leg length, that determine a great fit. That’s why you’ll see some overlap in our recommendations. Not every rider who’s 5´8˝, for example, will fit on the same size bike. The best way to find your perfect fit is to consult the experts at your local retailer.
