I've got an old 7 speed Shimano HG cassette but some of the teeth have worn making the chain skip. Is it possible to use a nice shiny 9 speed cassette on the freehub body by removing 2 sprckets and using the 7 speed spacers?
Actually I think I have a spare 9 speed (or 8 ) I'll give it a go....and it worked.
Although straight forward I took some pics along the way anyway:
Original 7 speed:
9 speed with smallest cog missing making it an 8 and useable in a 126mm OLN spacing:
9 speed SRAM cassette with Shimano 7 speed spacers and 2 cogs removed:
Only modification I had to make was cutting the lugs of the Shimano spacers:
And obviously I could not reuse the bolt that held the 9 speed cassette as it was too long, so just fitted without.

But as I said very straight forward.
