I have an old Giant Peloton Lite. Certainly considering its age, it's a very nice bike. The front chain ring is a bit worn out, however, and I'm looking to replace it. I have a few questions about that:
- It seems like a relatively easy job. Screw the old one loose, put the new one on. I've seen a video about it, which seemed to confirm that. I like doing small maintenance, so I like to do things myself if possible (instead of taking it to the local bike shop). Is this true, or is it really something I should have my LBS do?
- As for parts: my current ring is a 53-teeth, I found a 50-teeth in the same make. Can I use that, or will that give me unforeseen issues?
- In general, what are things to look out for in chainrings? I'm very new in learning about these things, so I'm curious what are the relevant factors determining my bike's compatability with a given chainring. The chain, for sure. But can one match a chain ring with a very different cassette or freewheel, provided they run on the same type of chain?
- It is generally recommended to change the cassette (or freewheel) if you are changing the front ring. Is that really necessary? The freewheel is still really good.
I know these might sound like naive questions, but, I'm learning and having fun doing that. Thanks for your help.
(To further specify: it's a 2x6 Exage 500 drivetrain)
