Hi all.
Not the most interesting or exciting of maintenance enquiries, sure, but, I could use some help...
Helping a friend with an old 90s hybrid, and it seems the freehub body is on its way out. It keeps releasing when it's not meant to release.
So, new freehub body, I suspect. So I take a look.
Shimano FH-RM30.
Here's where it gets tricky. Sticker on the hub says '8 speed', but the cassette is 7 speed. I remember from working in a bike shop in the 90s that some of us were rolling round with 7 speed cassettes on 8 speed hubs, with little spacers taking up the slack on the freehub body.
I didn't have proper tools with me to take a look, but I peered behind the cassette and couldn't see a 7-to-8-speed spacer.
So it comes to this:
Should I be recommending by friend get a 7 or 8 speed freehub body? Or must it be dismantled before ordering, to see what's going on in there?
Or have I completely misunderstood what's needed?
The freehub bodies are different from 7 to 8 speed. These may help:
Cheers JoeG, but that's kind of my problem:
On a FH-RM30 hub marked "8S", but sporting a 7 speed cassette, which variety of freehub body should I expect to be lurking within?
