I'm gonna replace my cassette and chain
Alright folks, heres the deal. I went a long time, over 5500 miles on my bike since it was new. I never replaced the chain. the cassette autoshifts when theres too much load on it, and I have a feeling that the chain is so freakin stretched it isn't even funny (though I haven't measured it). I'm going to replace the whole shebang, and I was wondering if I should replace the chainrings also. If it makes a difference, its an ultegra cassette, shimano chain, 105 crank and rings, and very old dura-ace shifters.
