U.P. (Unbeaten Path) combines a performance-oriented cross/road geometry & parts with clearance for mountain bike tires. So you can ride anywhere, and ride fast. Get out of town on asphalt, hit the gravel roads or switch to singletrack. The geometry gets you there fast; the big tires make you unstoppable. The U.P. fits 650b mountain bike tires up to 2.1” wide. But you can also fit a 40mm cross tire, or a 28mm road tire, or anything else in-between (exact tire sizes depend on manufacturing tolerances and rim width, so this is a guideline. Always make sure you have 6mm clearance between tire and frame). Fully-internal cables External cables collect dirt, risk getting stuck behind objects (particularly expensive with electronic shifting) and frankly, they are ugly. So the U.P. runs them internally. With our proven MultiStop design, you can customize the frame for 2x10/11, 1x10/11 and Di2 shifting. Just pick the right insert. In case you run a single chainring, you can also remove the front derailleur hanger to further clean up the frame. The U.P. uses the 386 EVO bottom bracket standard. The wide (86mm) BB shell is perfect to attach the dropped drive-side chainstay to. Furthermore, it fits most of the cranks on the market, from Shimano, Campagnolo and SRAM (the GXP versions) but also smaller brands like THM, Rotor and RaceFace. 386 EVO even allows for the installation of many mountain bike cranks. Chainring fit: Max inner ring: 36t Max outer ring: 50t (more is overkill with the bigger tires) Max single ring: 46t (offset rings like SRAM 1x) Max single ring: 50t (flat rings, better cassette alignment) Headset std: Integrated Tapered IS42/28.6 | IS52/40 Seatpost Ø: 27.2mm Rear axle std: 142x12mm thru axle Rear brake std: Flat mount for 160mm disc Cable routing: Internal via exchangeable MultiStops for 1x10/11, 2x10/11, Di2 Bag mount: 100mm front-post-to-bearing-bore-edge Included: fork, headset, seattube collar, front thru-axle, spare rear derailleur hanger

On the race course or on the way downtown, Hayes CX Expert mechanical disc brakes offer up smooth, controlled stopping power no matter the weather. Contact points are covered by Salsa cockpit components and an All-City saddle, a winning combo whether you're on your way to work or the podium.
