Joining the all new OneUp Carbon Handlebar is the OneUp Stem. Designed for everything from trail riding to Enduro racing. If you are running a OneUp Carbon Handlebar, this stem has a small mark designed to be used to help you centre your bar and stem - scroll through our images to see how it works.

The OneUp Stem can be used with a regular star nut and top cap like every other stem. It's also compatible with EDC top caps, for people who've already threaded their steerer tube.
