With a string of awards and titles under its top tube, the Open U.P. is facing increasingly stiff competition as the gravel trend spreads. Now the already iconic U.P. has seen some major updates – but are they enough to keep it ahead of the curve?

Here you’ll find our current group test on the best gravel bike.

Open U.P.
Open U.P. | 7.68 kg | € 3,200 (frameset)

In our previous issue we ran a group test of endurance bikes, pitting the Open U.P.P.E.R., with a frameset retailing at € 4,500, against bikes in the current top echelons of the market. It came out shining. At the most recent Eurobike, there was bated breath as Open launched the revised Open U.P., which relies on the same geometry, the same features, and the same tire clearance as the U.P.P.E.R that first came out in spring. The main difference lies in the U.P.’s slightly more price-conscious carbon layup that results in a heavier frame; we’re talking 1,040 g for the new U.P. frame while the U.P.P.E.R. has a lithe 880 g frame weight (manufacturer’s stats). Boasting upgrades to the inaugural generation of the U.P., this latest iteration features flat mount disc brakes along with the super sleek and more precise Open U-Turn fork, which had previously been reserved for the top-shelf U.P.P.E.R. The Open U.P. also cuts a good figure for bikepacking. You want to know everything about bikepacking and bikes, gear, route planning and accommodation? Click here for our detailed Bikepacking 101.

Additionally, this version makes use of a more sophisticated and practical thru-axle design. The frameset retails at € 3,200 and comes in green, blue, or a ready-to-paint option. The black carbon stealth vibe is still the preserve of the U.P.P.E.R. Our test bike came kitted with premium carbon components from Easton, 40 mm wide Schwalbe G-One tires, and a SRAM Force groupset. At the cash register you’re looking at around € 6,000 and a total weight of 7.68 kg for the large size frame.

Tuning-Tip: Purely for aesthetics we’d suggest switching the bar tape for a neutral colour.

Fuck, that’s fast! The Open U.P. is like a mountain goat on the climbs and it’s unstoppable in full flight. The Easton bars are 440 mm wide, serving up a relaxed position on the hoods and a racier position on the drops. There’s a gentle flair to the bars which adds stability and a sense of confidence on singletrack trails. In addition the flare works amazingly well with the SRAM Force brake levers, adding more confidence. The Open steers with precision and predictability, forgiving poor line choices with the sort of good-natured shrug that you’d expect from bigger tires. Of course, this bike’s tire clearance means you can always mount 650b wheels with mountain bike tires when occasion demands. Despite coming up slightly narrow on the rims the specced 40 mm tires provided ample comfort, so going up to 650bs would certainly elevate this.

There are no question marks about this bike’s ability to have fun – That’s a guarantee whether you’re entry-level or elite

Details like the tidy cable routing, well-considered spec, and bottle cage mount options are worth applauding, and the U.P. demolished the rest of the group test in terms of design and cables. Take a glance down at the ground while riding this year’s U.P. and you might wonder if the bike even has any cables, they’re so innocuous. However, what’s certainly unmissable is its green paintjob and blue bar tape, which the most design-conscious among you might not dig. The same applies to the Easton carbon seatpost that looks more akin to a Stone Age club. The SRAM Force 1×11 drivetrain with a 10-42 cassette gives you a great gear range, although the steps between the gears are fairly substantial.

Beautiful cable routing: From above you barely see the cables and you won’t hear a peep from them on the trails either.

Classic Open: The dropped chainstay on the right leaves space for the 1x drivetrain and adds stiffness. The Easton cranks are ultra lightweight and easy on the eye!

Easton, what were you thinking? Do we need a firearm license for this carbon post?
