Build a custom rear Jra or Industry Nine Classic MTB wheel with this wheel builder. Use the separate front MTB wheel builder linked at the foot of this page to make a matching pair.
Industry Nine "Classic" hubs have normal flanges to use J-bend spokes, and so we can offer custom wheel builds on them in this online wheel builder. Classic MTB hubs are available in either Centerlock or 6-bolt versions to suit your bike, all options are shown below with estimated stock status and lead times. Industry Nine Classic rear MTB hubs can be supplied with axle kits to fit all the usual standards, and Shimano or Sram XD freehubs.
Jra hubs are the same as used on our in-stock wheelsets and are fitted with the same high quality stainless steel bearings. They have 54 points of engagement (48 for centre lock hubs). There are versions to fit most bikes and axle kits are available to convert to most common standards.
Rear hubs cannot be converted to or from Boost standards.
This builder includes our recommended choices for building MTB wheels.
Remember that for disk wheels, braking forces as well as drive are passed through the wheel. Sapim D-Light are great for strong, light wheels while Race spokes can be used for extra strength at the expense of about 40g per wheel extra weight. Aluminium nipples weigh about 10g per wheel, brass 30g. Brass are tougher and last longer, aluminium come in lots of nice colours and the Sapim aluminium nipples we use are very durable (just not as corrosion-resistant as brass).
Valves are optional, but are discounted in this builder when you buy them at the same time as wheels.
