Whenever I look at this it always seems complicated
I want to install say Tiagra shifters etc
So I need
- Cassette
- Shifters = presumably two so they match
- Rear derailleur
- Do I need a new chain? I suspect so
- Do I need a new Chainset? I hope not - I am on 50-34 at present
I look at it and I see that some rear deraillleurs only go up to 28 or 30 - I read in forums such as Cyclechat that you can sometime make them cover more. Presumably if I fit a new shifter the fron deraileur will work as before with it.
No I will happily ditch the 11 on a cassette - could even do without 21 but most cassettes start with these. I don't know much about cassettes, and I know Nigel changes cogs - presumably he has some other cassettes as they don't seem to be individually available.
Conclusion is I also decide I don't know enough to know what I am doing
