Renthal Apex Stem Info
The Renthal Apex Stem is machined from a single piece of aluminum — shaped to deliver the stiffness you need when the trail gets rough without carrying unnecessary weight up front. The reversible design gives you a +/- 6-degree rise option, letting you dial in handlebar height without buying a second stem. Available in lengths from 31mm to 90mm, it covers a wide range of fit preferences across trail, all-mountain, and cross-country builds.
The two-piece, four-bolt face plate provides even clamping pressure across your bar — important when you're running carbon bars or pushing hard on technical terrain. The 31.8mm clamp diameter and 1-1/8" steerer interface are standard across the range, making fitment straightforward on most modern mountain bike setups.
