OPEN x ENVE New UP Gravel Frameset - Limited Edition

  

ENVE limited edition of the U.P. The original performance gravel bike, combining a performance-oriented road geometry & parts with clearance for mountain bike tires up to 2.1". Start on asphalt, hit the gravel, switch to single track. Its geometry makes you fast; its tires unstoppable. Limited to 60 units worldwide.

The New U.P. retains the performance-oriented road geometry & parts with clearance for mountain bike tires from the original. Start on asphalt, hit the gravel, switch to single track. Its geometry makes you fast; its tires unstoppable. The New U.P. accepts flat-mount brakes and ships with an OPEN U-turn fork.



Tyre clearance
The U.P. fits 650b (27.5") 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). You’ll hardly notice a difference in geometry swapping 700c cross/road and 650b mountain bike tires on the U.P., while 29er tires would make a total mess of the handling. There is a second reason we designed for 650b and not 29er tires. They would require very long chainstays, while the U.P. now sports a very short 420mm rear end. Most gravel and cross bikes have longer chainstays than that yet they can't fit anywhere near the same size of tire.

Crank clearance
Behind the bottom bracket, the chainrings, frame and tire all fight for space. And with the need to fit big mountain bike tires and narrow Q-factor cross/road cranks & chainrings, the U.P. presents the toughest possible packaging problem. Dropping the right chainstay moves it out of this crowded area, allowing it to be wider and therefore stiffer (a huge effect; with the same amount of material, twice the width will give you eight times the stiffness!).

U-turn Fork
We designed a new fork that accepts flat-mount calipers without the need for an adapter. So you can get your Shimano or SRAM flat-mount caliper, remove the standard adapter it comes with, and bolt it directly onto our fork. This saves weight and increases the stiffness of the braking system. We do this by making the fork dedicated for 160mm brake rotors and using the same through-bolt design that is normally reserved for the rear. Some may not like the exposed bolt heads on the front of the fork leg instead of them being hidden, but we actually like it. It’s a technically superior design, so this engineering choice should be clearly visible. But the U-turn fork doesn't just save you weight on the flat-mount brake, it is also extremely light itself. At 375 grams, it is by far the lightest fork that fits GravelPlus tires.
