Open U.P. Frame Kit - Blue - Small
This frame is incredibly versatile, and further blurs the line between road and mountain bike disciplines as a class leading cyclocross bike. The 3 members of the U.P. (Unbeaten Path) range from OPEN all combine a road riding position with clearance for mountain bike tyres. Get yourself out of town on an adventure. Leave home on asphalt, then start grinding up gravel roads or carving down some flowy singletrack. Your riding position gets you there quickly and efficiently; the big tyres give you the grip and confidence you need to feel unstoppable. Every U.P. and U.P.P.E.R. frame shares the same shape, geometry, intended use and most importantly: tyre clearance. But they differ in the layup of the carbon fibre, weight, fork, disc brake mounts, thru-axles and colour. The Classic U.P. uses post-mount disc brake mounts, whilst the New U.P. and U.P.P.E.R. use flat-mount disc brake mounts. Features Tyre clearance - This frame fits 27.5” (650B) mountain bike tyres up to 2.1” wide. But you can also fit a 40mm cross tyre, or a 28mm road tyre, or anything else in-between (exact tyre sizes depend on manufacturing tolerances and rim width, so this is a guideline. Always make sure you have 6mm clearance between tyre and frame). So you’ll hardly notice a difference in geometry swapping 700c cross/road and 650b mountain bike tyres on this frame, while 29er tyres with their significantly larger radius would make a total mess of the handling. There is a second reason Open designed for 650b and not 29er tyres. They would require very long chainstays, while this frame now sports a very short 420mm rear end, enabling much quicker, more responsive handling. Most gravel and cross bikes have longer chainstays than that yet they can’t fit anywhere near the same size of tyre. Crank clearance - Dropping the right chainstay away from the crowded area behind the bottom bracket let us build it wider and therefore stiffer (a huge effect; with the same amount of material, twice the width will give you eight times the stiffness!). TRCinTRS technology - Making a frame entyrely out of 100% high modulus (stiff) carbon is not a good idea, especially when there are areas like the headtube that receive big impact loads. Stiffer carbon is more brittle, so it’s not appropriate for all parts of a frame. Wire-stays - Lateral stiffness in the rear triangle is required for an efficient drive train, but vertical compliance allows for better comfort. This frame features chainstays and seatstays that are exceptionally thin vertically to give you that compliance, whilst their lateral width and carbon fibre layup still ensure rock-solid propulsion. Truly the best of both worlds. Flat-out downtube - The downtube is the key for stiffness, connecting the steering centre of your frame with the drivetrain. The flat-out downtube’s characteristically flat outside faces allow us to strategically place strips of ultra-high modulus carbon far away from the centre plane. This is especially a big plus on rough terrain. Zero-setback posts are lighter, saving you another 10-30 grams. So the U.P. runs them internally. With our proven MultiStop design, you can customize the frame for 2×10/11, 1×10/11 and Di2 shifting. Just pick the right insert. If you run a single chainring, you can also remove the front derailleur hanger to further clean up the frame. 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? How? The ThruThread design uses the same threads that hold the thru-axle to lock the derailleur hanger into the frame. Simple, light, effective.
