Can a deore 9 speed rear mech be setup for a 7 speed system ??

[Pete A]

Dont know if anyone can advise, Ive got a modern deore 9 speed rear
mech, and am in the process of upgrading an old Dawes Galaxy to a 7
speed setup - is there any way this can be used, or do I need to go
for ones that specifically say suitable for 7/8 speed ?

I'll be fine. I've done it with an XT rear mech.

The indexing isn't in the mech, it's in the control (lever or twistgrip
or whatever). If you want it to index correctly you'll need a control
which pulls exactly the right amount of cable to move the mech through
the gear spacing on your cassette, and that may be tricky; but if you
use a non-indexed lever it will work fine.

I've replaced a naff tourney derailleur with a deore mechanism. Took
only about 10 minutes (although it took a couple of days to fine tune
it in actual use). Mine's a six speed setup too not seven.
