OneUp Components Stem

This stem is specifically designed for 35mm diameter handlebars. Please double-check your handlebar clamp diameter before purchasing, as it will not fit 31.8mm bars.

The stack height is 39mm. This is a standard measurement, but ensure you have enough steerer tube length remaining on your fork to accommodate it.

A shorter stem, like the 35mm option, typically makes steering feel quicker and more responsive, while a longer 50mm stem can provide a bit more stability and a slightly more stretched-out riding position. Choose based on whether you prefer snappy handling or a more planted feel.

Yes, it is engineered specifically for trail and enduro use. The 6061-T6 aluminum construction and wide four-bolt clamp are built to handle the high stresses and vibrations of technical terrain.

The opposing-bolt design provides consistent, even pressure on the steerer tube. This helps prevent the stem from twisting or slipping under heavy load while ensuring your headset adjustment remains stable.
