Our strongest wheels feature a 37mm internal width rim extruded in 6069 aluminium to stand up to any type of riding. The massive rim width provides excellent stability to tyres, tubeless or not, from around 2.4 to 3.2″ width. Built for strength not light weight, these wheels come in at 2190g but the great handbuilt quality keeps them lively. Great for e-bikes too.
Rims and hubs feature laser-etched Wolf graphics.
Available in 27.5″ and 29er wheel sizes.
We used the best hubs we could find for our range of wheels and hubs: Bitex. We have ridden them extensively and we are convinced that they offer outstanding durability, reliability and serviceability.
All jra hubs are fitted with sealed stainless steel bearings from TPI and Enduro. Freehubs feature a patented 6 pawl engagement with 48 points in road hubs and 54 point pick-up for MTB hubs.
