Which Hex Key for My Freehub?
I need to service (or replace) the bearings in my freehub and I'd rather buy only one hex key. Anyone know of it's 11mm or 12mm?
It's the "Giant Tracker Performance" hub on my '12 Trance X1.
Thanks in advance.
Shimano free wheel bodies use a 10mm key... It's usually cheaper to buy a set of keys than just one.
10mm is too small; but thanks for the reply.
Turns out it's a Formula hub and it takes an 11mm hex.
Thanks for coming back to post the answer.
The bearings have gone in my freehub so I needed to know as well.
The freehub is way to fiddly to service: tiny bearings everywhere, and the race is probably toast anyway.
Look for a Class A chromoly freehub. They're easy to find and only about $25. Don't get the alloy freehub, it's not the same fit.
