Some love the action, some ride to relax. So we offer this page in two themes:   ZEN ROCK & ROLL

MONSTER TIRES, NIMBLE RIDE

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.

WHAT IS THE WI.DE.?

  • With 650b gravel or mountain bike tires up to 2.4”(61mm), 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

REVIEWS

Bicycling

“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.”

RoadBikeAction

“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.”

Cyclist Magazine

“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.”

Bicycle Quarterly

“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.

Podia

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

Gran Fondo

“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!”

Bikeboard.at

“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.”

DOUBLE-DROP CHAINSTAY

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.

TIRE CLEARANCE

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” (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

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.

Equally important is the handling as we have a reputation to protect (check out the media reviews about the U.P. handling).

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

TRCinTRS™ TECHNOLOGY

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.

U-TURN

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. Check the specifications for more details on how to mount each brand of caliper.

“STUFF CARRYING CAPABILITY”

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.

WIRE-STAYS

Vertically thin chainstays and seatstays provide compliance, while their lateral width and layup ensure rock-solid propulsion. Truly the best of both worlds.

FLAT-OUT DOWNTUBE

The downtube drives stiffness, connecting your steering center to your drivetrain. The flat sides places strips of ultra-high modulus carbon where it matters most.

ZERO-SETBACK SEATTUBE

A zero-offset seatpost is lighter & more efficient, so we have designed our seattube angle such that most riders can use a zero-offset rather than an off-set seatpost.

INTERNAL ROUTING

Internal cables & hoses stay clean & protected and frankly, they look better. Our MultiStop design accepts 1x, 2x, mechanical, Di2 and eTap.

THRUTHREAD DROPOUTS

Lock bolt secures the hanger in the frame using the same threads that secure the thru axle on the other side. Simpler, lighter & optimized for the stiffest thru-axle: Syntace X-12.

SMARTMOUNT

SMART-MOUNT 160

Flatmount brake calipers attach directly onto the fork & frame, positioned for 160mm discs. No front or rear adaptors/spacers required.
