The OPEN WI.DE. is living the supple life on its huge 650 x 54B tires and with numerous features on offer, is fighting for gravel dominance. So let’s get to it. How does this gravel bike on steroids fare in direct comparison to the competition?

OPEN WI.DE. | 8.28 kg (size L) | € 3,200 (frameset) | € 7,100 (complete build)

OPEN have a unique mission: “Work hard to stay small!” Staying true to their credo, the team of Andy Kessler and Gerard Vroomen put a huge amount of thought into the concept for their newest model. The WI.DE expands on the already gravel-focussed range from the Swiss brand, joining the U.P. and U.P.P.E.R. in the lineup for € 3,200 (frameset only). It maintains the typically tidy OPEN design language but offers sufficient clearance for impressively large tires: 700 x 46C or 650 x 60B. But thanks to the “Double Drop” chainstays, the frame is still compatible with standard q-factor road cranks. Along with space for tires, the frame offers plenty of mounting point for bottle cages and bags. That allows you to carry luggage on mounting points on the down and top tubes, as well as under the bottom bracket. For the latter the low position improves weight distribution, offering a sensible place for heavier items like your tool kit. Somewhat tongue in cheek, OPEN are also clear on the fact that they don’t set much stock by labels of “100% hi-modulus aero-space carbon” but take a more reasoned approach. According to them, it’s all about using the right carbon in the right places – TRCinTRS™.

Room to spare
Despite their aggressive tread and large 650 x 54B measurement, the frameset effortlessly swallows the Schwalbe G-One Bite TLE tires.
Mounting option
There are bosses underneath the bottom bracket to mount a tool box. The position and low centre of gravity have minimal impact on handling.
Double gravel trouble
The “Double Drop” chainstays allow standard road cranks with a narrow q-factor to be installed, despite the huge tire clearances.
Size matters
The combination of SRAM AXS mountain and road drivetrain parts results in a huge 500% gear range.

The OPEN WI.DE. in review

The dimensions of the WI.DE might imply a sluggish ride but step on the pedals and it’s anything but. At 8.28 kg in size L, it’s one of the lightest bikes in our group test and it springs wilfully forward from a standstill or out of corners. On the road, it’s only the tread of the Schwalbe G-One Biet TLE tires that robs the OPEN of top marks in terms of efficiency. The combination of low weight and the SRAM AXS drivetrain consisting of Force eTAP AXS shifters and cranks, and Eagle AXS derailleur and cassette with a 500% range ensure the OPEN can surmount any terrain. Having scampered up the steepest of slopes, this bike shows its particular prowess on technical terrain. It stays composed even while rolling through fist-sized scree, turning gravel adventures in the remotest locations into a true pleasure to ride.

Tuning tip
A second 700C wheelset, for an even more versatile bike

The OPEN marches inexorably forward through technical terrain, like Obelix through the amassed Roman ranks.

The specially constructed rear end means that the WI.DE offers good compliance and comfort despite its zero-offset seatpost, matching the comfortable front end perfectly. The 90 mm stem also creates a compact and upright position which increases comfort further. As a result of the high volume tires, pressures can be correspondingly reduced, further improving the rolling characteristics of the 27.5” DT Swiss wheels. However, you might have to play around a bit to find the pressure that works best for you and to avoid a vague and spongy feeling ride.


The WI.DE expands OPEN’s portfolio with a gravel-specialist specifically for the rough stuff. If you want to ride almost exclusively off-road on your expeditions, you’ll find an incredibly well thought through option here. With 700C slicks, the OPEN transforms into what is likely the most comfortable road bike around. However, if you put more stock in all-round characteristics but are a fan of what OPEN does, then you should take a closer look at the U.P.(P.E.R.).


  • capable on very technical terrain
  • quick acceleration
  • coherent and thoughtful build


  • slightly limited all-round performance in this off-road build
  • you’ll now have to buy both the U.P.(P.P.E.R.) and the WI.DE.
