Guys,

Quick question, if upgrading my rear mech from 9070 to 9150, would I need to adjust the chain length at all (short cage to short cage version).

Thanks a lot!

My experience was that while the 9150 rear derailleur cage was a bit longer, the direct mount link also added a bit, so I went with a new chain that was two-links longer.
