I've acquired a pair of old Alexrims DC 4.5 Disc 26" MTB wheels with Formula hubs, but the rear wheel is missing the axle. I've been reading various posts about how to measure / replace the axle, but haven't found anything that makes me confident enough yet to buy a replacement. Is there an easy way to tell what size / type I need?
I initially presumed I would just need a standard axle for 5mm QR skewers, but when I measured the internal diameter of the hub it was 12mm. So is this hub actually designed for a 12mm bolt thru axle?
Any advice or pointing in the right direction would be greatly appreciated!
