Renthal Apex MTB Stem – All-Mountain Performance, XC Weight
When you need a stem that doesn’t make compromises, the Renthal Apex MTB stem is the answer. Developed with input from elite enduro and cross-country racers, the Apex is built to handle everything the trail throws at it — from technical enduro descents to punchy XC climbs — without adding unnecessary grams to your build.
Unique 240° Handlebar Clamp Design
At the heart of the Apex’s engineering is Renthal’s innovative 240° handlebar clamp system. By wrapping around more of the bar than a traditional four-bolt clamp, the design allows a significant portion of stem body material to be removed while actually increasing clamping strength and stiffness. The result is a stem that’s lighter, stiffer, and more secure — exactly what modern wide mountain bike handlebars demand.
Fully CNC Machined Precision
Every Renthal Apex stem is fully CNC machined from high-grade aluminium, with an oversize centre bore, deep 3D material removal, and external webbing running through the stem body. This approach maximises structural rigidity and strength exactly where it’s needed, while stripping every gram of unnecessary weight from areas where it isn’t. It’s the kind of obsessive engineering detail you’d expect from a brand that supplies components to World Cup and Enduro World Series athletes.
Why Choose the Renthal Apex?
Renthal has been a trusted name in motorsport and cycling components for decades, supplying handlebars and stems to some of the world’s best riders. The Apex stem reflects that heritage — it’s not a budget component dressed up with bold graphics, but a genuinely engineered piece of kit that performs in the real world.
Whether you’re building up a trail bike, refreshing your enduro rig, or upgrading from a stock stem, the Renthal Apex delivers the stiffness, strength, and weight savings to make a noticeable difference to your ride.
Compatible with: Most modern mountain bike forks with a 1-1/8″ (28.6mm) steerer tube.
