OPEN UP WIDE Extreme Gravel Frameset - Grey
The WI.DE. (Winding Detours) can run even bigger tires while still fitting road cranks! The monster tires help you conquer the most extreme terrain, the performance geometry & narrow Q-factor keep you efficient while the steering geometry keeps you nimble.
- With 650b gravel or mountain bike tires up to 2.4”, rutted singletrack, slippery roots and loose rocks are no match
- With 700c gravel tires up to 46mm, even the toughest gravel roads are tackled at lightning speed
- With 700c road tires (we recommend 35-40mm wide), you have the most comfortable road bike ever invented
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.
Finding ways to fit the biggest possible tire into a bike with road geometry and road cranks is one of our specialties. The WI.DE. does this thanks to the double-drop chainstays mentioned above and a dedicated 1x frame design. Since most of our customers run 1x drivetrains, we can use the inner chainring space to move the chainstay outward and increase tire clearance. As a result, the WI.DE. comfortably accepts up to 2.4” tires in 650b (or 46mm on 700c wheels). Actual tire width depends on tire model and rim width, so measure instead of relying on the tire label.
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!).
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.
