Open WI.DE Gravel Frameset

The Open WI.DE (Winding Detours) takes gravel grinding to the next level of gnar. Instead of one, both chain stays are dropped, allowing 2.6" 650b and 46mm 700c tires! If a road bike is like a Ferrari, and the UP is a Ford F-150, then the WI.DE is Mercedes G-Wagon that's been lifted.


The OPEN U.P. inspired a generation of gravel bikes that could fit up to 2.1” tires. 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.


The U.P.’s dropped chainstay has became Open's most copied frame feature ever. No wonder, as it is a great way to create more tire clearance.

The WI.DE. goes one better. By dropping both chainstays, the monostay just behind the bottom bracket becomes a very efficient box structure. This increases BB stiffness, reduces weight and squeezes even more tire clearance out of the frame.


Finding ways to fit the biggest possible tire into a bike with road geometry and road cranks is an Open specialty. The WI.DE. does this thanks to the double-drop chainstays mentioned above and a dedicated 1x frame design. Due to the popularity of 1x in gravel, Open decided to 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.


Most riders know that with the right bike geometry, even big tires can be fast. The WI.DE. takes this to the extreme. Of course a massive tire is not as fast as a pure road tire, but the delta is small enough that it doesn’t detract from the on-road fun. And off-road, there is no comparison.

The WI.DE. retains its agility with anything from massive mountain tires to road tires.


Open U-Turn fork have always had massive tire clearance, making it the perfect match for the WI.DE. It’s also very light, thanks to another OPEN innovation: Smartmount.

Smartmount attaches the caliper directly onto the fork, without any adaptors. The mounts are positioned pre-set for 160mm discs (the only sensible choice for gravel bikes). Lighter, cleaner, stiffer and safer.


As your Wide Detours get wider, you want to take more stuff but without it getting unwieldy. So you can mount an extra bottle under the downtube and a toolbox under the BB, ideal for stability.

The tool box mounts are off-center to create extra clearance to the chainring. If you don’t use a toolbox, you can mount a larger water bottle under the downtube.

The WI.DE. is also designed to take a (strapless) toptube bag as well as saddle, handlebar and frame bags for longer high-speed adventures.


Internal cables & hoses stay clean & protected and frankly, they look better.


A zero-offset seatpost is lighter & more efficient, so Open designed the WI.DE's seat tube angle such that most riders can use a zero-offset rather than an off-set seatpost.
