This axle set will allow you to convert Gran Compe wheel sets, or hubs to fit in to the ends of a 110mm spaced keirin frame. This is a special order item, and sometimes can take up to a week to restock before shipping. Please note that shipping may take a few days more than expected. This kit works perfectly with the Gran Compe track hubs. It does NOT work with the NJS-certified Gran Compe PRO version, or the Gran Compe II (2) series hub. Contact us with a photos of your hub/wheel if you need confirmation of compatibility.
