Shimano Compatibility
#1

Good afternoon,

I have an old mountain bike I want to do up. It has Shimano Altus RD-CT90 rear derailleur, controlled by a worn out ALTUS ST-CT90 shifter (7 speed) - which I want to replace.

My question is, what can I replace the shifter with? Will any 7 speed Shimano shifter do, or does it have to be the same as the original?

Many thanks

Dafydd

do you have 3 rings up front? check out the Shimano st-ef51 in the 7speed flavor. great replacement for the dollar

In addition to almost any Shimano (certainly any reasonably price Shimano) shifters; you can also use SRAM MRX and TRX series.
