Rotor 3D24 172.5mm Track Crankset With Aero Spider 144 BCD and 48T Chainring. This is the 24mm spindle version (good news if you have a BSA bottom bracket!). I have a slightly used Rotor Italian BB if you are interested (must request if you want it included). I will detach the spider from the drive side crank for ease of shipping, so you will need to reinstall the spider upon receipt (it’s just a few torx screws).

This crankset came on a track bike I bought that was very lightly used (it was a local frame builder’s own bike and I don’t think he had much time to ride it). Crankset has very few signs of wear (look at the chainring teeth), selling because I built the frame up with parts I already had. Let me know if you have any questions.
