Hi :)

excuse my ignorance here :oops:

My bike has XT shifters and an XTR M972 rear shadow mech , Im not sure of the mechanics but it has the ability to double shift , is this the shifters or the deraulieur that gives it this ability ?

eg if i change the mech to a Saint will I lose this ability ?

Also if anyone can be be bothered to explain how it does this I would be very grateful :)


cheers

    Nice one Nick , thank you :D

    So am I right in thinking that with the right shifters any shimano mech will double shift ?

    eg , XT , saint etc ?

    reason for asking is that my rear pulley cage , the carbon one, snapped in half on my local black run , as they are nearly £100 replacement cost for the set :( , I think i may swap it for a saint , especially as my bike runs a 2 ring set up.

    cheers

    I'm a roadie, but the basics are the same. Your shifters are pulling (or releasing) a given amount of cable, and that amount of cable causes the shift (double or otherwise) to occur at the mech.

    just make sure the mech is 1 the same size and 2 has the same movement ( rapid rise or normal)
