Open U.P Cyclocross/Gravel Frameset  promises to be one of the best ever gravel bikes. The product or true passion and heaps of experiance the new UP has everything you could ever want from a cross or Gravel frame.

U.P.’s geometry is performance-oriented, so closer to a cross/road position than a mountain bike position. Combined with clearance to fit mountain bike and road/cross cranks, this gives you a comfortable and efficient position to far and fast on any terrain.

U.P. also fits the widest range of tires – even mountain bike tires – so not even the toughest conditions can stop you. We've placed a great emphasis on compatibility for U.P. The rear axle is 142x12 thru-axle so you can fit your 29er and 650b mountain bike wheels. The BB standard is BB386 EVO so you can fit virtually any crank you desire (rather important since the frame is meant to accept both mountain and cross/road cranks). Headset, seatpost, everywhere we've gone with the most common standards as long as they made sense.


ThruThread dropouts
Most thru-axle frames are heavier than quick-release frames. Extra carbon for the dropouts, heavy hangers, and the axle itself. But they are stiffer, So what do you want most? The answer for most people is “both”, and so we introduce the first frames that combine a thru-axle with a lower weight. How?

  1. The ThruThread design uses the same threads that hold the thru-axle to lock the derailleur hanger into the frame. Simple, light, effective.
  2. We didn’t just redesign the dropout, the entire seatstay and chainstay design is optimized with the added stiffness of the thru-axle in mind.
  3. For the thru-axle itself, we choose the stiffest design available, the Syntace X-12.

afePost™ Pilot hole
Seatposts usually indicate a minimum insertion dimension. While it is important that there is enough seatpost inside the seatTUBE to support the former, it’s only half the story. The seatTUBE also needs to be supported properly, and therefore requires a minimum insertion. Simply make sure the seatpost is inserted past the SafePost Pilot hole AND past the minimum insertion stated on the post and you’re good to go.

TRCinTRS™ technology
 “100% hi-modulus carbon”, “aero-space grade”, etc. Useless – and hopefully false (we’ll get to that) – claims meant to impress you.

It’s not about high- or low-modulus, it’s about the right carbon in the right spot. And because the bike industry loves techie-sounding abbreviations, we’ll humor them and call it TRCinTRS™

Fact: stiffer carbon is more brittle. Strategically placed ultra-high-modulus carbon is a good idea. Making the whole headtube out of it when you have big impact loads is not!

The best lay-up is not 100% of one modulus; it’s a blend. We use the highest modulus (stiffest) carbon of any bike manufacturer where we can, and tougher grades of carbon where we must. That’s how our frames are both light and durable.
