About our wheels: JRA hubs

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 freehubs have 6 individually sprung pawls for quick, reliable engagement. The pawls work in two sets of three, resulting in 48 (road) or 54 (MTB) points of engagement with reliable performance under tough conditions.



Anti-bite guard
Anti-bite inserts prevent cassette gouging. Three stainless steel splines inserted into the freehub add almost no weight while effectively preventing the cassette from digging in to the softer aluminium.






Well sealed

Fitted rubber seals on both ends of the freehub keep dirt and water out.


Stainless bearings by TPI

TPI Stainless Steel bearing are the best we have found and we have specified them in all of our hubs except in a small number of bearing sizes that are not available. In that case we use TPI steel or Enduro instead. They make up a large proportion of the cost of the hub but they run smoother and last longer than any others we have tried.



JRA disk hubs are convertible between all the main axle types by changing the end caps or axle, depending on the model.
