Industry Nine Hydra hubs (f&r) Boost - XD - 6 Bolt - 32 Hole- Threaded Spokes in brand new unused condition however they were removed from a new wheelset so they do have a few minor marks from the removal process . These are the much rarer threaded spoke version that use industry nine spokes . The front hub is 15x110mm and the rear is 12x148mm both hubs are boost spacing . Please ask if you have any questions.
