We Are One's revolutionary handlebar and stem combo is newly renowned as one of the lightest and most durable options available for the downhill-focused rider. This innovative product aims to tackle a common problem encountered with conventional bar-stem interfaces by delivering precise and optimal clamping force.
Through extensive fatigue testing, We Are One discovered the potential hazards of connecting a regular stem to a carbon bar. Bar failure often arises from irregular clamping force, a low tolerance bar diameter, and harsh interactions between the bar and stem.
The design of this handlebar and stem combo stands out for its unique simplicity. It effectively distributes force throughout the entire sleeve area by maximizing the clamping surface and incorporating a patent-pending location nipple. This carbon nipple not only guarantees perfect alignment but also secures the sleeve in place to prevent rotation.
Da Bar, with its 33mm diameter, has been specifically engineered to enhance flexibility while accommodating the 35mm clamp diameter of Da Stem. This approach introduces a fresh perspective on the traditional 35mm concept, providing an optimized solution for handlebar and stem integration.
All For One
DA BAR
Out of the mold at 800mm wide, with inlaid marks allowing for precision cutting down to 740mm. Offered in 20mm, 27.5mm, and 35mm rise options with a 5° up-sweep and a 8° back sweep.
DA STEM
Machined from a billet of 7075 aerospace-grade aluminum, Da Stem takes 6 operations from a solid block to a raw stem before being anodized black to ensure a long-lasting product.
Da Stem comes in at a svelte weight of 80g for the 35mm and 88g for the 45mm option. Finished off with a set of 4 rolled thread titanium fasteners, this is one of the lightest and strongest stems on the market!
DA PACKAGE
All in the combo is 332g for the 35mm option and 340g for the 45mm option. One of the lightest DH-rated combos out there.
