- 10 or 11spd chain for geared bike or 6-8 spd for SS. If used in a 1x9 drivetrain, a 10spd chain must be used for proper retention (yes - 10spd chains will work great on 9spd cassettes).
- No, but chain length is important as you won't run a clutch-type rear mech. A short cage derailleur is highly recommended.
Important information for SHIMANO derailleur users -
- In order to get best results we recommend increasing the cage return spring tension. New derailleurs are assembled with the spring in the mount that allows the most relaxed position of the spring. However, there is another position on the cage which will increase that tension. It is a standard procedure; you might want to ask your LBS to do it for you.
- Sram users are not required to do this as their springs are already in the high tension position.
