What customers say
The OneUP Stem earns high praise primarily for its ingenious integration with the OneUp EDC tool system. Riders value the convenience of having essential trail tools securely stowed inside the steerer tube, often eliminating the need for bulky bags on shorter rides. This unique feature is considered a significant market differentiator. Beyond tool storage, the stem itself is lauded for its robust build quality and precision machining, providing a solid, secure feel on the trail without creaking or slippage. While initial setup requires minor effort, the long term utility and thoughtful engineering deliver excellent value. It is a highly recommended upgrade for riders seeking both performance and unparalleled convenience.
Know before you buy
The OneUp Stem is available in three lengths: 35mm, 42mm, and 50mm. This range allows you to fine-tune your reach and steering responsiveness based on your frame geometry and riding preference.
A shorter stem, such as the 35mm option, typically provides quicker, more direct steering input. It can also help if your bike's reach feels too long, bringing the handlebars closer to your body for a more upright, controlled position.
The OneUp Stem is designed to fit standard mountain bike handlebar diameters. Please ensure your current handlebar matches the clamp diameter specified for this model before installation.
Beyond its sleek aesthetic, this stem is engineered for increased stiffness and reliability. It creates a more secure connection between your handlebars and fork, which translates to more precise handling and confidence on technical terrain.
No, this specific model is offered exclusively in a black finish. This neutral, understated look is designed to complement any bike frame color or component build.
