This stem was developed and tested as a unit with our (Handlebar Carbon). Even though the 1 Piece Stem 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 or oil slick bolts, drop us a message before you place your order, and we will set you up.

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.
