Description
Renthal built the Apex 35 clamp for riders who keep bending or cracking stems on rocky enduro trails and rutted moto tracks, and the 50 mm version gives you the low, race-style perch that experienced racers ask for by name. Instead of a solid forged block, Renthal machines a distinctive 240 degree clamp face that lets the factory pull material out of the stem body in exactly the spots where it is not carrying load, so you get a lighter part without giving up the stiffness a wide modern handlebar needs when you are hammering through whoops or landing off a step-down.
What makes the Apex 35 different
- 3D machined stem body with external webbing keeps flex in check while trimming excess mass
- 240 degree clamp geometry spreads clamping force across a wider contact area than a basic split clamp
- Engineered specifically around 35 mm oversize handlebars, the standard on current-generation off-road bikes
- 50 mm bar height puts the cockpit in a lower, more aggressive stance favored by taller or more aggressive riders
Fitment is straightforward: this clamp is sized for 35 mm bar setups at a 50 mm mounting height, so confirm your stem spacing before ordering since Renthal offers this same Apex design in multiple heights. IPD Racing stocks the Apex line because it is one of the few aftermarket clamps that actually improves on stock geometry rather than just swapping colors, and it bolts in using your existing hardware with no special tools required.
Renthal designed this clamp as part of a modular Apex system, meaning the stem, top clamp and hardware are all engineered together rather than adapted from an older bar diameter. That matters on race day, since a mismatched stem and clamp combination is one of the more common ways riders end up with a loose or creaking cockpit after a few hard landings.
