I'm looking to convert from a Triple Ultegra setup to a Compact.
I'm currently running a newer Ultegra triple (6603 "new style" Ultegra) with a long cage 9-speed rear Derraileur and a 9 speed rear hub.
- If I move to a Compact, can I run a 10-speed short cage rear Derr. with my current setup or do I need to find a 9-speed rear Derr given the 9 speed hub? I'm looking at an FSA Gossamer Mega Exo Compact.
- Can I use my current front Ultegra Triple Derr. or do I need to get a new one?
- Anything else I need to get or be aware of?
- Is this worth doing or should I just stay with the triple? (I live in the San Francisco Bay Area so I do *occasionally* use the small front and large rear cogs - not often but it happens.
Thanks for your help!
