I discovered a Shimano FC-2300 Crankset (175-mm 52/42/30T 8 Speed) for $62 on Amazon - is this compatible to replace my old FC 3301/3304?
The longer story is I need to replace my Shimano chain (CS-HG50) / middle chainring from an SG 52-42-30 set (and I expect rear cassette too?) after 5 yrs of a modest commute on my 8 speed flat bar bike.
Can anyone recommend an online seller of suitable replacement parts compatible with the Sora FC 3301/3304? My local shop in Perth Australia proposes to sell me a new bike, but I'd rather repair to safe and functional level - I won't be winning any races on this unit:) I'm new at the repair work and tho' I've got a chain tool, it appears I'll also need to get special tools (crank extractor?) to get at the chainrings? Do I also need special tools for to replace the rear cartridge? Thanks in advance, Chris
