the silver/grey ones they were knocking out a couple of years ago, SRAM Apex. Anyone know what the freehub is please?

Its a formula hub – Mine went after 1000 miles and i ended up relacing the wheel onto a new hub. Couldn’t find a freehub for it.

The one I worked on had the formula cartridge hub- nice hub but pretty much unavailable in the aftermarket I think. Obvious question but have you tried Halfords?

Just a thought, I’ve got a lightly damaged wheel with what I’m pretty sure is the same hub in it, from a Halfords voodoo… Could possibly come to some deal on that if you’re interested. But it might make more sense just to rebuild onto something with better availability
