Open Cycle OPEN WI.DE.

The U.P.’s dropped chainstay has become our 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 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.

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.

Forget “100% hi-modulus aero-space carbon”. It’s not about high- or low-modulus, it’s about the right carbon in the right spot (or TRCinTRS™ as we mockingly call it).

Fact: stiffer carbon is more brittle. So it's great for stiffness (on the sides of the downtube) but bad for impact loads (for example around the headtube).

Hence the best lay-up is a blend. We strategically place the ultra-high modulus (very stiff) carbon where we can, and tougher grades of carbon where we must. That’s how our frames are both light and durable.

Our U-Turn fork has 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.
