please go easy me as it is my first post!
this is link to the bike model (there a tab for the tech specs)
Shimano HG-50, 8-speed, 12-25t
Forged alloy, double-sealed, cassette, QR, 32h
I have been riding a road bike for the last six months and clocked up about 2500 miles doing so, when a few days ago I noticed occasionally when coasting at a slow speed my freehub isn't freewheeling.
Obviously this is an issue with the freehub, I don't want to take it to the LBS as I like to know how things such as this work, so the problem lies in where to purchase a replacement and compatible freehub body as I don't really understand the relating acronyms. So could anyone recommend what model type I should purchase and where from?
Also the freehub presently on my bike seems to take a 11mm Hex key which seems odd as I assume it to be a Shimano freehub and from what i have read it is usual for all shimano freehubs to fit a 10mm hex key?
