A super-light Enduro Stem with a 35mm clamp that you can rely on. The smart one-piece construction allows for low weight while being sturdy and stiff. You can choose between 7 different colors and the lengths 35 and 45 mm, so you can customize your bike and adapt it to your personal needs. The assembly with the 77designz carbon handlebars is a piece of cake, but also handlebars from other manufacturers can be mounted with up to 20 mm rise. The 35mm short stem weighs an incredibly light 69 grams, and its 45mm counterpart weighs only 84 grams. Titanium screws are included, and we have passed a DH-level Test at the EFBE test laboratory.

This stem was developed and tested as a unit with our (Handlebar Carbon 35). Even though the One Piece Stem is fully approved to be used with other handlebars, it is not allowed to spread it, which might make it difficult to use it with other handlebars. The minimum clamping area at the steerer is 39mm.

Custom Bolts:

For our stems, we use entirely custom made titanium butted screws with a Torx 25. If you want to switch to golden, natural or oil slick bolts, drop us a message before you place your order, and we will set you up.

Tested at the highest level:

We see no difference between Enduro and Downhill racing; that's why our products get tested on Downhill Level (ASTM F2043-13 / Category 5).

The Collaboration with We Are One!

The concept idea for the cockpit comes from us, but for the implementation, we needed a reliable partner who is well versed in carbon fabrication, we found this partner with We Are One Composites. We Are One has enriched the handlebar with the small retention nipple on the handlebar which holds the aluminum ring in position. We Are One filed a patent for this idea. We are One Composites from Kamloops / BC in Canada is the manufacturer of our handlebars and distributes a conceptually identical cockpit in North America.
