Versatility is an understatement with the U.P, and its ability to run both 700c and 27.5" wheels lends it a wide swath of applications when paired with both. A set of 32mm slicks on the 700c wheels and 2.1" knobbies on the 27.5" set essentially turns it into two bikes in one. The slack seattube angle is designed around a zero-offset seatpost for proper setback, and the Open UP is capable of running both 2x and 1x drivetrain setups, though we tend to tilt towards SRAM's Force 1x11 setup. The U.P is also dropper seatpost compatible, and one of our favored setups uses a 1x drivetrain with 2x shifters, using the left-hand SRAM trigger to actuate the dropper mechanism.
