Open UP / UPPER 2.0 Gravel Bike
Explore the hotly anticipated version 2.0 editions of OPEN's seminal UP and same-but-lighter UPPER gravel framesets.
Both frames deliver the balance of light weight, nimble handling, and comfort that allows a rider to move quickly across any surface
Ten years after the U.P. redefined what a gravel bike could be, OPEN has introduced the next evolution: the UP 2.0 and its lighter sibling, the UPPER 2.0. Building on the proven performance, market-leading tech and comfort of its first editions, both models refine the ride experience with a host of updates that leave no stone unturned on the trail to gravel bike perfection.

More about the Open UP and UPPER 2.0
The UP 2.0 and UPPER 2.0 carry forward the qualities that made OPEN’s gravel bikes defining in the first place, while refining them for today’s riders. At their core, both frames deliver the balance of light weight, nimble handling, and comfort that allows a rider to move quickly across any surface. Whether the goal is a fast gravel race, a long day linking varied terrain, or keeping pace on a smooth tarmac group ride, these bikes are designed to adapt without compromise.
To go faster and farther requires both efficiency and ease. The new framesets preserve OPEN’s renowned compliance while adding aerodynamic shaping in key areas. The result is reduced drag where it matters most, without sacrificing the ride quality that allows riders to stay comfortably in position for the long haul.
It's a simple thing that you should feel so comfortable, but that's the essence of an Open bike.
Tire clearance is optimized for 35–46mm, giving the UP 2.0 and UPPER 2.0 a sharp, responsive character across gravel, dirt, and road. For riders seeking the ability to run even larger rubber, the WI.DE. continues to provide that option.
The construction follows OPEN’s full-carbon, closed-shape philosophy: no inserts, no clamp cuts—just continuous fibers for optimal stiffness, strength, and weight savings. Ten frame sizes are available, each with cockpit adjustability that allows stem length to be fine-tuned in 5mm steps up to 15mm.
Manufacturing takes place in Portugal under the principle of "Made in Freedom." For OPEN, cycling represents freedom, and that ethos guides the brand's decisions about where and how to invest in production. But don't take this line as a knock to its former Far-East production center - to OPEN, freedom means closer to home and the latitude to iterate and engage with its manufacturing partner where the brand lives and rides: in Europe.
Finally, the UP and UPPER 2.0 deliver details designed for riders who value time on the bike over time in the workshop. Features such as a UDH hanger, a T47 threaded bottom bracket, and thoughtfully engineered internal routing make setup, adjustments, and servicing straightforward. The result is a frameset ready for performance, built with durability, and prepared for years of worry-free use.

A Closer Look
The Open B.a.r.
The one-piece bar-stem is reinterpreted in the OPEN B.A.R. It combines a continuous carbon structure with a patented internal clamp system that allows stem length adjustment in 5mm increments—without compromising weight or stiffness. In many cases, adjustments can be made without disconnecting brake hoses. With ten sizes available, a precise fit is always within reach.
Fork Options
Two forks support the UP/UPPER 2.0, each in five sizes: U-Turn Aero: optimized for aerodynamics, with integrated brake caliper and clean lines - standard on both UP 2.0 and UPPER 2.0. And U-Turn Adventure: designed for compliance and cargo compatibility. Standard cage mounts and OPEN's patent-pending ultralight cargo system make it ideal for longer expeditions.
Aero Front, Comfort Center
OPEN prioritizes aerodynamics where they are most effective: at the front of the bike. The headtube, fork, bars, and downtube are refined to reduce drag, while carbon layup and shaping preserve comfort over long rides. Further back, comfort takes precedence. The seat tube, chainstays, and seatstays are shaped to deliver compliance without compromising efficiency. The ultra-thin seatstays also reduce frontal area and are subtly profiled for airflow.

About the brand
Open Bikes
OPEN is a bike industry outlier. Its business model, predicated on the concept of “working hard to stay small”, is 180 away from almost every carbon fiber bike brand, who see bigger as undoubtedly better.
