Help choosing chain and cassette
#1
I have a ~2003 Marin Larkspur that needs a new cassette (8 speed) and chain.

How do I choose the right chain and cassette for this bike?

Are all 8-speed cassettes interchangeable and just differ in quality?

Do I just need to get a chain that says it's for an 8-speed cassette?

UPDATE: I found a manual online for a 2005 model of my bike. Says the chain is IG31 and the cassette is an 8-speed 11-32.

Yes, any 7 or 8 speed chain and any 8 speed cassette. 11-32 is the # of teeth, I don't climb hills, so I don't buy cassettes with an upper # above 28. Some of the guys here have favorite brands, but you can use any of the common ones, Shimano, SRAM even Sunrace.
I like a chain with a removable link for easy service & cleaning. Some of the links are flimsy IMO (Bell). The chain just has to be 3/32 x 1/2". which is super common.
You'll need a chainwhip, a cassette tool & a chain tool.

As Jeff says, almost any Shimano compatible 8 speed cassette will work.

I disagree with him chains - you need an 8 speed or higher rated chain - I found this out the hard way when I tried to use a 7 speed chain (with a 7 speed cassette) and 8 speed RD - lots of noise from the RD as the chain went through it. The 7 speed chain was too wide for the 8 speed RD. Many chains are rated for more than one speed, just make sure that the rating includes 8 speed.

Personally, I like SRAM chains, and am planning on trying KMC next time around.

On the cassette; which gears do you currently use? There are wider and closer ratio cassettes available. I do not have real hills to deal with on my rides, and am planning on going with this one when my green GT needs a new cassette:

Currently has a 11-30 Shimano, the closer ratios are appealing to me with my old knees.

These will fit:

Interesting. I have an acera RD that is noisy with a KMC 7.3mm heavy duty 8 speed (x8.99) chain. Perhaps I should try their 7.1mm models.
