I have a set of Giant Mike Burrows wheels with EXT PRO Hubs. The freehub is crunchy and has play in it. I have sourced a Joytech freehub which fits the Giant (Joytech) hub in terms of the locating splines but it does not accept the 12mm axle and M18 torx fixing bolt (non drive side). The one I sourced only takes 10mm axle and is secured with an M16 bolt. Both secure from the non drive side. I have exhausted my internet searching.
Where can I source one that takes the 12mm axle and M18 torx bolt for fixing.
