My 2007 Dahon folder needs a new cassette and chain after 2 years of commuting 15 miles per day. From the specs I've seen on various websites, my bike has a KMC Z82 chain and a Shimano HyperGlide 8 speed, 11-32T cassette, but I'm planning to replace them with higher quality components from the same manufacturers:
Shimano STX HG50
KMC X8-93 8 speed chain or
KMC X8-99 8 speed chain
Will these be okay for my bike and will they be compatible? I'm planning to buy and get them fitted by a local bike shop.
Also, when replacing chain and cassette is it advisable to also replace the chain ring?
Thanks in advance
