The world's first flatmount fork that doesn't require an adaptor. Thanks to the direct-mount design, the set-up is simpler, stiffer and lighter (only 390g). Fender-ready mount on the inside of the fork crown and fork race integrated in the carbon steerer (so fork race provided with the headset should not be installed).
Included in box: Fork, steerer expander,
For the U.P.P.E.R., Open 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.
Open did this by making the fork dedicated for 160 mm brake rotors (140 mm is a bad idea anyway on this type of bike) and using the same through-bolt design that is normally reserved for the rear.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. And to save even more weight, it is comes with an extremely light 12mm Carbon-Ti custom axle
So the U.P.P.E.R. ships standard with the U-turn. Since the U.P. is a post-mount frame, it ships with a post-mount fork, the 3T Luteus II.
