Monster Tires, Nimble Ride

The WI.DE. (Winding Detours) targets bigger tires than the U.P. without compromising speed.

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.

What is the WI.DE.?

1
With 650b gravel or 27.5" mountain bike tires up to 2.4”(61mm), rutted singletrack, slippery roots and rocks disappear.


2
With 700c gravel tires up to 46mm, even the toughest gravel roads are tackled at lightning speed
3
Assembled with 700c road tires (we recommend 35-40mm wide), you have the most comfortable road bike ever invented.

Double-Dropped Chainstay.

The U.P.'s dropped right chainstay launched a whole category of bikes. The WI.DE. doubles up.

The double-drop chainstays create a very efficient box-shape behind the BB. This increases stiffness, reduces weight and boosts tire clearance.

Tire Clearance.

Fitting the biggest tire into a bike with road geometry is our favorite puzzle!

The WI.DE. maximizes tire clearance with its double-drop chainstays and a front-derailleur-free frame design for 1x or 2x setups. Using 1x cranks, there is no inner ring or front derailleur to limit tire clearance. You can either run that as a classic 1x setup as most of our customers do. Or you can go 2x using the Classified system: light, fast, very efficient and clean.
As a result, the WI.DE. comfortably accepts up to 2.4” (61mm) 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.

Speed & Handling.

Thanks to its efficient rider position, the WI.DE. is deceptively fast on-road despite the big tires. This always surprises first-time WI.DE. riders. So great fun on-road and no limits off-road.

Equally important is the handling. The WI.DE. retains its agility with anything from massive mountain tires to road tires. Trigonometry helps us a bit here, as the trail automatically grows together with the tire size, just like you want for tougher terrain.

TRCinTRS™ Technology

So many marketing claims about carb on.
But the truth is quite simple.

„100% hi-modulus aero-space carbon”. It’s not about high- or low-modulus. In 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).

Every bike company has access to the same carbon (volume is too small for custom or exclusive). So all these different names for proprietary carbon are just that, names.
What matters is that high-modulus carbon is more brittle than low-modulus. So in areas where strength is important, high-modulus is the wrong choice.
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.

U–Turn.

The U-Turn has tire clearance in abundance. It’s also very light, thanks to another OPEN innovation: Smart-Mount.

Standard, the bike industry uses four bolts plus an adaptor to attach the brake caliper to the fork. This allows for flipping between 140mm and 160mm rotors. 

However, SRAM and Shimano both always recommend 160mm for the front, so we remove the adaptor and two bolts to attach the caliper directly onto the fork for that rotor size.

This makes the setup lighter, stiffer, safer. (Check our Specifications for the correct bolt lengths for each setup.) 

This design also cleans up the U-Turn fork legs and allows us to make a very light structure with very tunable stiffness and strength.

„Stuff Carrying Capability”.

Extra bottle under the downtube and a toolbox under the BB. Ready for every Winding Detour.

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.

Design is in the details.

Reviews & Awards

“Open continues to raise the bar on how far you can take a road bike off road and still have an agile, fast rolling, rollicking good ride. The WI.DE. blows the roof off tire size options & is impressive on technical singletrack, going further than the Open U.P. ever could. I cleared large boulders and even hopped fallen trees pretty easily.”

– Bicycling

“Overall, the Open WI.DE. is pushing the boundaries of where we can take a drop-bar bike and what they shouldlook like. The crazy part is that, thanks to its aggressive geometry, it does an amazing job on the road, too.”

– RoadBikeAction

“Having been riding gravel bikes all week, it was immediately evident how much more confident the [WI.DE.] was on the challenging terrain. That’s partly down to the wider 2.4” tyres, but the geometry also seemed to play a part. The front end was lively, darting around rocks and through cracks but never in a way that disturbed the stability of the bike. The striking element of the WI.DE. though, was how much it still felt like a road bike.”

– Cyclist Magazine

“Auch verflog meine anfängliche Skepsis gegenüber des 650B Laufradsatzes nach den ersten Offroad-Abstechern in tiefsten Morast und über rutschige Wurzelteppiche und ich war schnell dankbar über das spürbare Plus an Grip und Traktion. Wirklich überrascht war ich allerdings über die Performance in der Ebene. Denn auf einem Gravelbike hatte ich wirklich noch nie einen solch breit bereiften 650B Laufradsatz unterm Hintern, der auf Asphalt dermaßen gut und schnell rollt. Love.”

– Bikeboard.at

“First impressions are… well, the WI.DE. is really amazing. I never thought that I’d want tires wider than 54 mm, but now I am riding with 24% more air.” Bicycle Quarterly video review.

– Bicycle Quarterly

“The WIDE feels planted and sure footed, it feels just so competent on any surface.”

– Podia

“With the WI.DE., the Swiss two-man-gravel-brand presents a very powerful bike. The balanced handling, huge tire clearance, and numerous mounting points for mudguards, drinking bottles and bags make it the ideal platform. The high level of comfort and safety will appeal to gravel fans of all skill levels. This frameset could be a very solid base for your next multi-day adventure bike or sporty after-work fun-rig for technical terrain. And yes, bigger is better indeed!”
