WEAREONE Composites Da Package

Anti crimp sleeve
In collaboration with 77 Designz we have manufactured one of the world's lightest and strongest bar and stem combos. The issue we tried to improve was the clamp force creating weak points at the bar to stem clamp interface. Testing and fatigue have shown that the interface between a regular stem and carbon bar can be hazardous. Irregular clamping force, low tolerance bar diameter, and harsh interactions between the bar and stem are the root cause of these issues.




Our unique, yet simple design maximizes clamping surface area while spreading the clamping force through the whole area of the sleeve. With our patent pending location nipple on our carbon bar. With the carbon nipple, you can ensure alignment is perfect and capture the sleeve so it does not rotate. Da Bar has also been designed to a 33mm diameter in order to drop the stiffness and allow for the sleeve to slide into our 35mm clamp diameter of Da Stem. A new way of thinking about 35mm.


Smart design meets absolute manufacturing excellence!

Tech Spec:
