The OneUp Direct Mount Stem keeps a downhill cockpit low and simple. Developed around OneUp's World Cup riders, it uses a 45mm length and zero stack in its base configuration. A separate spacer kit lets you add up to 10mm of rise when you need a taller position.
The CNC-machined aluminium body weighs 155g and uses a 60mm-wide clamp for 35mm handlebars. Four direct-mount bolts and four bar-clamp bolts are included, giving you the hardware for the stem itself while leaving the height-adjustment kit as a separate choice.

The zero-stack base keeps the handlebar close to the crown. The separate OneUp spacer kit adds up to 10mm of rise, so you can adjust the front-end height without changing the stem length.
