Open UPPER 2.0 (SRAM Red AXS XPLR) Size M

OPEN U.P.P.E.R. 2.0 SRAM RED XPLR AXS Gravel Bike

The OPEN U.P.P.E.R. 2.0 SRAM RED XPLR AXS is an ultra-light carbon gravel bike designed for riders who prioritise speed.

Ten years after the original OPEN U.P. helped define the modern performance gravel bike, the U.P.P.E.R. 2.0 takes the concept further with lower weight, refined aerodynamics, size-specific engineering and a completely integrated carbon cockpit.

Combined with SRAM RED XPLR AXS 1x13 electronic shifting and an integrated power meter, this flagship build is designed for gravel racing, fast mixed-surface rides and riders looking for road-bike speed with genuine off-road capability.

Ultra-Light U.P.P.E.R. 2.0 Carbon Frame

The U.P.P.E.R. 2.0 is the lightweight flagship of OPEN's latest gravel platform.

Its carbon frame weighs approximately 880 g ±3%, creating an exceptionally light foundation for a high-performance gravel bike.

OPEN has retained the frame compliance that made the original U.P. famous while adding aerodynamic optimisation where it matters most. The result is a bike designed to remain comfortable over long distances while reducing drag at higher speeds.

The frame is manufactured in Portugal and uses size-specific engineering to maintain consistent handling and ride characteristics across the size range.

SRAM RED XPLR AXS 1x13

This flagship U.P.P.E.R. 2.0 build features SRAM RED XPLR AXS, SRAM's top-level gravel-specific electronic drivetrain.

The 1x13-speed system combines fast wireless electronic shifting with a wide gearing range designed specifically for modern gravel racing.

An integrated SRAM RED power meter provides accurate performance data for training, pacing and race-day efforts.

SRAM RED hydraulic disc brakes deliver powerful, predictable braking for technical gravel descents, fast road sections and changing conditions.

Designed for Fast Gravel

OPEN has designed the U.P.P.E.R. 2.0 specifically around 35–46 mm tyres, creating a platform focused on speed rather than maximum tyre volume.

This allows riders to choose fast 35–40 mm tyres for smoother gravel and mixed-surface racing or move towards higher-volume setups for additional grip and comfort on rougher terrain.

The result is a gravel bike that feels equally at home racing on dirt roads, riding fast on tarmac or linking both together on long mixed-surface routes.

U-Turn Aero Carbon Fork

The OPEN U-Turn Aero fork complements the aerodynamic front end of the U.P.P.E.R. 2.0.

At approximately 375 g, the U.P.P.E.R.-specific fork contributes to the exceptionally low frameset weight while helping reduce aerodynamic drag.

OPEN also uses size-specific fork designs, allowing the geometry and handling characteristics to remain consistent across different rider sizes.

OPEN BAR Integrated Carbon Cockpit

The U.P.P.E.R. 2.0 features OPEN's innovative OPEN BAR one-piece carbon cockpit.

Rather than using a conventional separate handlebar and stem, the closed carbon structure reduces weight while eliminating metal inserts and clamp cuts.

The cockpit also provides 15 mm of stem-length micro-adjustment, allowing the rider's position to be fine-tuned without replacing the complete integrated cockpit.

Combined with fully internal cable routing, it creates an exceptionally clean and aerodynamic front end.

Modern UDH & T47 Platform

The latest U.P.P.E.R. 2.0 uses a UDH – Universal Derailleur Hanger, making it fully compatible with SRAM's latest XPLR drivetrain technology.

A T47 threaded bottom bracket combines the stiffness and dimensions required by a modern performance frameset with straightforward servicing and maintenance.

These standards help make the U.P.P.E.R. 2.0 a thoroughly modern platform while retaining OPEN's characteristically simple and functional approach to bike design.

From Gravel Racing to Fast Road Rides

The U.P.P.E.R. 2.0 isn't limited to gravel.

OPEN specifically designed the bike to be capable of fast tarmac group rides as well as gravel racing and mixed-surface adventures.

Its low weight, aerodynamic front end and responsive handling give it a road-bike character on smoother surfaces, while wider tyres and gravel-specific components provide the control required when the route leaves the asphalt.
