Enduro Stem 35mm for Trek Knockblock

 cSixx Enduro Stem - Trek Knock-block compatible

A product that we’re incredibly proud of and has been a long-time passion project, our cSixx Enduro Stem, designed for aggressive Trail, Enduro and Bike Park laps is engineered to be the best possible product available.

We have crafted this product from a specifically chosen grade of 6082 T6 extruded aluminium bar to perfectly align the aluminium grain for maximum durability, strength and fatigue resistance.  A 40mm Stem clamp height perfectly optimises the torsional stiffness and using our inhouse testing facilities have allowed us to surpass an equivalent of twice that of the ISO test standards most brands comply with.

Our easy to use Zero-Gap Bar Clamp seamlessly integrates with handlebars, guaranteeing a secure connection while carefully radiused outer clamp surfaces prevent stress concentrations on your handlebar enhancing durability of the Bar-Stem interface.  Available in 5mm increments from 35mm to 60mm and options for both 31.8mm and 35mm bar diameters, our Enduro Stem provides all the sizing options so you can dial in your bike for the perfect fit and feel.  

Customise the Stem to suit your bike by spec’ing a unique Anodized or Cerakote finish, both processed in-house, coupled with black treated Stainless-Steel bolts, for a custom look that complements your bike to make it your own.

Beyond aesthetics, our focus is on strength, safety, and durability. We prioritize the right balance, avoiding a blind pursuit of weight reduction in favour of finding the perfect balance between optimal weight and stiffness in crucial areas. Through the expertise of our in-house CNC machinists, designers, and engineers, excess material is meticulously sculpted away, resulting in a beautifully machined product built to withstand the toughest trails. Thanks to our in-house manufacturing as well as testing capabilities, you can be assured that our cSixx Enduro Stem is not just a component but a tailored solution, delivering the perfect strength, fit and feel for every ride. 

Please note that Custom colors can take up to 5 days to process and are not returnable.
