I've been battling against my chain for a while - it seems to be constantly noisy, even though I don't really use the bike that much at the moment. The chain's always kept clean and reasonably well oiled, so it's a mystery as to why it's being so noisy. Any ideas?
The other thing that's been getting to me is shifting up through the gears when I'm on the largest chainring; shifting through 1, 2, 3 is fine, but then it struggles to change up again until I try to go for 6th or 7th when it's fine again. Any ideas why this might be, and how to make it stop doing this? The indexing seems to be OK when it comes to shifting down, so I'm at a loss.
