The latest generation of the U.P.PER. adds more speed, even crisper handling and more tire clearance (up to 46mm true width) to its already legendary comfort and toughness.
Now more than ever, it is THE gravel frame that can hang with the roadies on pavement and take off when the roads turn rough.
The ultralight cockpit offers 15mm of micro-stem length adjustment in 5mm steps, while the size-specific design for frame & aero fork ensure the best experience regardless of rider height.
The U.P.PER. 2.0 is finished in carbon black with forest green downtube patch. The CHASSIS includes frame, fork, headset, seatpost and the OPEN B.A.R. integrated one-piece bar/stem.
