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 high quality stainless steel and plain steel bearings from TPI. Freehubs feature a patented 6 pawl engagement with 48 points in road and centerlock disk hubs and 54 point pick-up for MTB hubs.
Not all hubs take all end-caps. If you order something that doesn't work we will contact you, please get in touch if you need more information before ordering. You can check compatibily on the individual hubs spec. here >
Mountain bike wheelsets are built using the latest Stan's Notubes Mk3 Crest, Arch and Flow rims. The result of more than 10 years of continuous development these rims offer the best combination of weight, strength and tubeless performance available:
Crest Mk3 are designed for normal cross-country riding and racing. Weight is just 364g for the 29er rim, internal width is 23mm. Recommended tyre width 2.0-2.25".
Arch Mk3 are a strong, 26mm internal rim for heavier trail riding and for larger tyres; recommended tyre width 2.25-2.5".
Flow Mk3 are the development of the classic Flow and Flow EX rims for heavy riding and wide tyres. Tyre width 2.35-2.8".
All wheels are built in our York workshop using Sapim spokes and spoke nipples - see choices below for colour and spoke options. Sapim D-Light are our normal spoke recommendation for most riders with the thicker, heavier Race spokes available for heavier riders.
Sample wheel weights, real-life weights - we'll add more as we remember to weigh wheels when we've built them.
