Ten years ago, Open's original U.P. redefined what a performance gravel bike could be. The OPEN U.P.PER. 2.0 Chassis is the result of a decade of refinement — faster, lighter, and more composed than its predecessor, without losing the trait OPEN riders have always relied on: a ride quality that makes mixed terrain feel like less of a compromise and more of an advantage. This is the race-focused variant of the U.P. 2.0 family. Where the standard U.P. 2.0 adds cargo rivnuts for bikepacking, the U.P.PER. 2.0 strips it back to a superlight layup and an aero fork. The result is a gravel frameset that lines up at the front of fast group rides just as willingly as it does at a gravel race start.

The frame itself weighs 880g — painted, including the T47 threaded BB shell. The carbon layup is distinct from the standard U.P. 2.0, blending fiber types to balance stiffness with impact toughness across every part of the frame. Open's design philosophy — aero where it matters, comfort where it counts — plays out in the tube shapes. The deep headtube cuts drag where airflow is cleanest. The downtube is flat-sided to direct stiffness into the bottom bracket. Moving rearward, the wire-stays take over: thin, sideways-bowing seatstays that absorb road buzz without adding width or weight. The 425mm chainstays keep the rear end snappy across all five sizes, and the straight stays offer maximum tire clearance — up to 700x46mm — without demanding a wide Q-factor. Every size gets its own geometry and tube shapes, and the fork crown is sized individually to maintain the same agile, lively handling from XS to XL.
The U-Turn Aero fork is standard on the U.P.PER. 2.0 — fully aero blades at 375g, with an integrated brake caliper mount via Open's Smartmount 160 system. Smartmount eliminates the adapter and two extra bolts that standard flatmount setups require, attaching the caliper directly to the fork and frame for 160mm rotors front and rear. It's lighter, stiffer, and more rigid than what…
