If you could have only one bike, this might be it. One longtime tester said this ultralight version of OPEN’s gravel monster might be her all-time favorite drop-bar bike. It handles whatever you need for a day’s ride. On the road, the 16-pound U.P.P.E.R. has a fun, sporty feel even among race bikes.
On trails, it rides like a superlight race hardtail. Gravel? Rutted-out ATV tracks? Legit singletrack? With triple bottle-cage mounts, a top tube mount for a frame bag, and clearance for up to 27.5×2.1-inch knobbies, the U.P.P.E.R. is ready for the most adventurous rides.
