Gravel bike pioneer Open’s latest incarnation of the ground-breaking UP, the UP.PER 2.0 builds on the original striking design. The Swiss brand claims the new bike brings crisper handling alongside increased tyre clearance of 46mm.
The UP.PER 2.0 is described as the ideal bike for fast group rides on- and off-road, alongside gravel racing and bikepacking.
For riders looking for more clearance, Open offers the WI.DE frameset, or if you want a more all-road oriented lightweight design, there's the CONCE.PT, which we first saw at the COREbike show in 2025.
Open UP.PER 2.0 details
Open promises improved aerodynamics and frame compliance from the UP.PER 2.0 – the two factors that combine to enable faster and further rides.
As ever with Open, the details are everything, with the frame and fork having size-specific dimensions across all five sizes.
The size-specific fork crown is an industry first, ensuring the all-important handling is the same from the smallest to largest bike sizes.
Open is also offering two fork choices – a mount-less, deep-bladed aero option and an anything-mounts equipped, narrower adventure variant.
The made-in-Portugal frames come with a UDH-compatible rear dropout, T47 threaded bottom bracket shell and full internal routing.
Combined with the frame and fork is Open’s own one-piece aero cockpit, called the B.A.R. (available in 10 sizes from 60 to 130mm reach and 380mm to 440mm width).
All the cockpits feature a unique reach adjustment for the stem section. A second bolt sitting ahead of the usual compression bolt adjusts a slider system that can alter the reach by up to 15mm in 5mm increments.
The improved compliance comes from details such as the super-thin seatstays (named wire-stays). These have a bowed shape, which Open says is ‘pre-set’ to allow vibration-absorbing flex.
On the new frame design, the flex has been rotated 90 degrees so the stays bow out sideways under load instead of downwards as on previous incarnations.
While Open pioneered the original dropped-stay design to improve tyre clearance, the UP.PER 2.0 has much more aesthetically pleasing straight chainstays, yet maintains a 46mm tyre clearance.
Sensibly, Open has opted for a 27.2mm-diameter round post rather than a proprietary design. That means a wide range of suspension and dropper-post compatibility.
Price and weight details
The UP.PER 2.0 has a claimed frame weight of 880g, with the fork adding 375g.
The frameset (including the fork and bar system) is priced at £4,999 / $5,300 / €4,200.
Ready-to-paint custom
Alongside a wide range of standard colours, all of Open’s frames are available in RRTP (raw-ready-to-paint). As the name suggests, a finished frame is left raw and ready to be finished by a painter of your choice or one of Open’s partners.
The custom-paint option here is one of two, from the brand's partner in Italy, Tony Spray.
The build is a custom specification from UK Open distributor Silverfish, based around a SRAM Force XPLR drivetrain, running Easton EC90 AX gravel wheels and Michelin Power Gravel tyres, inflated with Peaty's new fast-flow tubeless valves.
It featurs an SDG Bel Air V3 Overland carbon saddle, sitting atop an Easton EC90 AX post. The brake rotors are Galfer’s lightweight Wave rotors.
A build like this would retail for between £9,000 and £10,000 before adding the custom paint finish.
