Industry Nine I9 Spokes

No, these are proprietary I9 system spokes. They are specifically engineered to integrate only with Industry Nine hubs and rims that utilize their direct-thread system.

Yes, provided you match the exact length and specification required for your specific wheel build. Because they thread directly into the hub, replacing one is straightforward, but ensure you have the correct length for your rim diameter.

Aluminum spokes are significantly lighter than steel, which reduces rotational weight and improves acceleration. However, they are stiffer and require a specific hub interface, which is why they are exclusive to the Industry Nine system.

Yes, you will need the specific Industry Nine spoke wrench or tool designed for their system. Because they thread directly into the hub shell, standard spoke wrenches will not fit or provide the necessary torque.

You must use the Industry Nine spoke calculator or consult your specific wheelset's technical manual. Because these spokes are part of a proprietary system, length is determined by the hub and rim combination rather than standard J-bend measurements.
