Mountain Bike Stems

A stem is one of the most overlooked components on a mountain bike, but it has a real impact on how the bike handles and how comfortable your riding position is. Length, rise, and clamp diameter all affect your fit and the way the bike steers. Getting your stem dialed is worth the effort -- and if you're not sure where to start, our MTB stem buying guide is a useful starting point for clamp size, length and fit.

Trail One Components -- Our Top Pick

Trail One Components is the brand we recommend first, every time. They make genuinely exceptional stems -- CNC machined, beautifully finished, and backed by a give-back model that funds trail building and maintenance. When you buy a Trail One stem, you're getting one of the best stems on the market and directly supporting the trails you ride. They make three models:

  • The Rockville Stem: Made in California. This is the flagship -- CNC machined aluminum, available in 35mm clamp, multiple colorways including black, bronze, and clear ano. If you want the best stem Trail One makes and want to support American manufacturing, this is it.
  • The Viking Stem: The linked model uses a 31.8mm bar clamp and 40mm length. Check those dimensions against your setup.
  • The Slickrock Stem: The linked model uses a 31.8mm bar clamp and 40mm length. Check the product page for its specifications and availability.

Other Brands We Carry

Renthal makes some of the most popular stems we sell -- the Apex 35 is a proven enduro-level stem that's been on a ton of race bikes. RaceFace offers options such as the Turbine, Aeffect and Chester. Check each model's dimensions and specifications. OneUp Components is another option to compare. Match the stem's clamp diameter to your handlebar. Industry Nine makes the A35 stem in custom mix-and-match colors for riders who want something unique. Thomson and ENVE round out the lineup for riders who want boutique quality.

Sizing

Match the handlebar clamp diameter and steerer size, then compare length, rise and stack height. This collection includes a range of lengths, so choose based on your bike's fit and intended setup rather than assuming one stem length suits every rider. Check bar and stem manufacturer requirements before installation. Any questions on what fits your bike, reach out.
