The UP (analogous: undeveloped path) combines a performance-oriented cross / road geometry with the tire freedom of a mountain bike. Thanks to the GravelPlus concept, you can drive almost anywhere and fast. Whether on the city on asphalt, on gravel roads or on single trails, the perfected geometry and the large tires of up to 2.1 inches (at 27.5 "| 650B) let you master any terrain without any problems.
The U.P. fits mountain bike tires up to 2.1” or 47mm RoadPlus tires in 650b. It also fits 700c gravel, cross and road tires from 28-40mm wide (exact tire sizes depend on manufacturing tolerances and rim width, so always check and make sure you have 6mm clearance between tire and frame).
DROPPED CHAINSTAY
Probably the most copied feature of the original U.P., but still few fully understand why and how to optimize this. Chainring(s), frame and tire all fight for space just behind the bottom bracket. Mountain (and some gravel) bikes solve this with a wider crank, but that hurts your pedal stance (Q-factor) and thus your pedaling efficiency. Instead we drop the right chainstay to move it out of this crowded area, allowing it to be wider and therefore stiffer (twice the width will give you eight times the stiffness!)
TRCinTRS™ TECHNOLOGY
Forget “100% hi-modulus aero-space carbon”. It’s not about high- or low-modulus, it’s about the right carbon in the right spot (or TRCinTRS™ as we mockingly call it). Fact: stiffer carbon is more brittle. So it's great for stiffness (on the sides of the downtube) but bad for impact loads (for example around the headtube). Hence the best lay-up is a blend. We strategically place the ultra-high modulus (very stiff) carbon where we can, and tougher grades of carbon where we must. That’s how our frames are both light and durable. .
U-TURN
The U-Turn is the first fork truly optimized for flatmount brakes. Standard flatmount front brakes include an adaptor to switch between 140mm and 160mm disc rotors. But nobody should ride 140mm rotors in the front, so it’s a feature without a benefit at the cost of weight, stiffness and complexity. The U-Turn’s Smartmount is a direct-mount with thru-bolts without adaptors, just like the rear brake. The position of the mount is adjusted to perfectly match 160mm rotors. Lighter, cleaner and safer.
