Cassette upgrade? Or like for like?
Chain, cassette and possibly chainset are going to be due replacement soon, although I may keep them going due to the weather and conditions at the minute, it's an hg50 with an octalink crankset and a Kmc x9 chain all on a 2009 rockhopper comp. Am I best off upgrading while I'm at it or going like for like? I was thinking same chain but hg61 cassette for the sake of 6 quid. Any ideas appreciated.
