I have an old 7-sp MTB, and was looking at the crankset while waiting for a train the other day. Starting to look a bit ragged, so I was thinking about replacing the chain rings.
It's square taper, which I think I can handle (just another version of removing a flywheel), but it looks like the chainrings are all welded to each other and the RHS crank.
Does thank mean I have to replace the lot? I'm assuming square taper cranks remain available, as do 7-sp cassettes?
TIA
