My commuter is a Sirrus sport. I do around 2,500 miles a year on it and it's done around 10K miles lifetime.
Yearly I change the rear cassette and chain (done last week). When the chain was off I noticed the rear derailleur was not running freely so I took it apart, cleaned it and seems better. I have also since noticed the large chain ring looks pretty worn. I only ever use the largest (of 3) so the other 2 are pristine.
My questions are:
1. Should I replace the jockey wheels/derailleur by now or is the clean sufficient?
2. I will change the large chain ring, I assume I can buy just the one and leave the others or do they only come in sets?
3. As I'll never need the other 2 is there any benefit to switching to a single ring or is that unnecessary work?
4. Whilst the cranks are off anyway, should I replace anything else?
Not too worried about costs, just don't want to do unnecessary replacements.
