Rolf Prima is on a mission to build their wheels from U.S. parts, going so far as to build their own alloy rim rolling facility. Now, they can add carbon rims to that list, too!
Made in the Pacific Northwest near their Eugene, OR, headquarters, the new rim is a tubeless ready, rim brake clincher that was two years in development. It’s laced to their TdF6.0 hubs, which get a “special ballistic coating” and use White Industries’ titanium Freehub body and newer T2 rapid engagement internals.
The result is the new Eos3 wheelset. Using just 30 total spokes between the two wheels, they weigh in at a scant 1295g…
Rolf Prima says the design is both light and aerodynamic, getting a 32mm deep, 25mm wide profile. They roll on Enduro Zer0 ceramic bearings.
“Several years ago we set out to do as much as we could in house and in the USA. In this project we chose one of the hardest things to develop: a tubeless compatible, light weight, rim brake carbon clincher. This required us to think more creatively and develop a new tooling system from the ground up, which was pretty exciting,” said Rolf Prima Senior Engineer, Joel Wilson. “The quality of tooling and innovative tooling design makes it possible to achieve the light weight rim that we were looking for.”
Price is TBD, expect them to ship in May 2016. We’ll have more info on these and several other new wheelsets from them at NAHBS this weekend.
