my main full sus bike has a shimano hg73 chain fitted. my commuter's chain is shot so im think partially worn chain off the full sus goes to the partially worn commuter and new chain on to the virtually new full sus cassette.
what spec is the hg73, or, what wont it fit on?
commuter has an 8 speed hg40 block and friction shifters
for the full sus is hg73 a good alrounder or is there better for simular money out there?
