We Are One carbon rims are hand-made in Kamloops, Canada. Founded by Canadian DH Champion Dustin Adams, gravity is in their blood.

Unlike most of their competitors, We Are One makes their own rims in-house. Not only does this make them great value, with one less middleman, the feedback loop between customer and production is much tighter. This means that learnings made from customers and athletes results in meaningful improvements much more quickly. 

The Convergence series is We Are One’s new, ultra-shallow and compliant rim. It looks incredible with a unique shape that also improves nipple/spoke interface. 

We Are One claims that this rim is stronger than the Revolution series, but having sold hundreds of both, we feel the strength is similar between both lines. 

Alpina Raggi Spokes and Nipples

The highest quality spoke and nipples, made in Italy since 1926.

Alpina is famous for its automation, which ensures consistency and quality whilst manufacturing wheel components. Alpina Nyloc nipples are particularly innovative, with a high 12Nm of locking force consistent throughout the lifetime of the nipple, no matter how many times they are adjusted. All Alpina spokes are guaranteed to be made from the highest quality European wire, unlike some of its closest competitors.

The Alpina Lite spoke is a double butted round spoke directly equivalent to the DT Swiss Competition.

The Alpina Ultralite Aero spoke is a bladed spoke directly equivalent to a DT Swiss AeroLite. Swapping to the Ultralite Aero spoke saves approximately 100g on your wheelset.
