OPEN U.P.PER. 2.0 SRAM AXS Custom Bike Info
The fast way off-road (and back again)
Why this frame matters
OPEN’s U.P.PER. 2.0 is the benchmark for riders who want one bike to do everything—fast. It’s ultra-light, razor-sharp on pavement, and shockingly sure-footed on gravel and singletrack. Big tire clearance (700c or 650b), a stiff yet forgiving layup, and clean routing make it the frame you choose when you refuse to choose between road speed and dirt freedom.
The U.P.PER. 2.0 is OPEN’s “go-lighter, go-farther” take on their cult-favorite U.P. geometry. You get the same confident fit and quick handling with a lighter carbon layup for snappier acceleration. Tire clearance to run fast 700x38–40c road/gravel setups or 650b x 2.0–2.1” for rougher days. 1x or 2x compatible, dropper-ready, and built around a precise fork and 12mm thru-axles for tracking that feels locked in. It’s the bike that makes detours feel like shortcuts.

About our Custom Bike Builder
Our builder shows real-time pricing and a live visual of your bike as you choose parts. It includes a wide range of options, but not every possible component on the market.
