Just about to buy a set of brakes and I'm trying to keep the cost down. I've got SLX (M666) on a couple of bikes but am trying to work out the differences with current Deores.
As far as I can see it's just the lack of tool free reach adjusmtent and non ceramic pistons on the Deore.
I'll be buying without rotors so no difference for me there and I wouldn't buy finned pads after the initial set wears out.
Are there any other differences?
