My bike is a few years out of date running 3x10 and using slx m660 shifters. The left hand shifter (front mech shifter) recently died (as in fell apart mid ride) so I've ordered a new one via flea bay. This arrived today but my old one is a m660a and the eBay one is a m660.
I know the old slx shifters came in 9 speed and 10 speed. My question to those more knowledgable is will this new one be ok on a 3x10 set up?
Thanks in advance.
I think I'm right in saying that front shifters are interchangeable between 9 and 10 speed.
Front shifters are the same for sram/shimano the only difference being ones designed for 2x or 3x shifting. Higher spec shimano can switch between both 2 and 3 chainrings
Thanks folks. I'll crack on and fit it and go for a ride then!
