Spacer on Shimano Hub?
I've been trying to figure out why the shifting on my bike doesn't seem too good and noticed that there is no shim behind the cassette, on the free hub.
The hub is a Shimano R500 and is compatible with 8, 9 or 10 speed apparently. With no shim fitted, the cassette feels secure.
My other wheels are Shimano RS30's and they are also suitable for 8, 9 or 10 speed. The cassette on there has the 1mm shim fitted.
Do all Shimano freehubs need the shim fitted if they're running 10 speed?

yes I think so unless they are 10 speed specific - which I think only applies to one model of dura ace hub.
the cassette might feel secure but could be moving under load when you're pedalling. Alternatively, could be any number of other things that are stiff, loose or out of tune...0 -
for an 8/9-speed hub, with a shimano* 10-speed cassette you need to fit the spacer (should be supplied with the cassette, but you can buy replacements)
* except for 10-speed tiagra cassettes, which, like sram ones, do not need a spacermy bike - faster than god's and twice as shiny0 -
where would i get a spacer from? i think i have a shimano 105 5600 cassette and my lockrings done up as tight as it goes and the cassette just wobbles, an do those plastic things which stop the chain hitting the spokes work as spacers?0

And no those plastic things (dork discs) do not act as spacers.0 -
I get confused with these spacers. Last year I was fitting an 8 speed cassette to a Mavis Aksium wheel. The instructions stated that a spacer (provided) should be use with a 10 speed cassette and yet the 8 speed cassette felt loose without it. I added the spacer just to see what effect would have and the cassette fitted perfectly. The gears change very smoothly so the spacer has no detrimental effect that I can see or feel. On the other hand, the 8 speed cassette without the spacer will not work.0

I agree with you as to regard the confusion.0 -
all covered in an FAQ. viewtopic.php?f=40101&t=12905742
a spacer is not always needed.
and if your cassette is not moving sounds like poor set up."Do not follow where the path may lead, Go instead where there is no path, and Leave a Trail."
