    M772 GS alignment issue

    M772 GS Shadow Medium Cage. Looks like the top pulley is a good 1.5in away from aligning with the small cass ring. What the crap? With no tension on the cable it auto jumps to the the third ring on the cass, theres no way limit screws can fix that much alignment. Ive made sure the der screw has been screwed onto the hanger right.

    Back out the high-gear limit screw, I seem to recall they ship them that way on purpose.

    What a coincidence, I just installed the same derailleur last night. Initially the limit screws were way off (3rd cog sounds about right, though not sure what you 1.5in comes from). Just back the screws out and they come right down!

    Sounds like you installed a new derailleur without adjusting the limits? Check both.

    ....and don't forget about the "B" tension adjustment!

    I dunno, starting to dangerously sound like following the installation instructions or something...

    Instructions, me?

    Ebay purchase, no instr. But I did back out the high limit WAY out and got it aligned. B screw. Never have figured out that thing in ten years of wrenching my own bike. This new XT design is really funky looking wonder how it will work.

    The first thing I do after bolting on a RD is adjust the high limit screw. It is SOP for installing any high-normal RD.

    The trouble with common sense is it is no longer common

    Hehe don't feel too bad... I would guess that the 80% of bike mechanic's that I had the pleasure of working with, over the years, had no idea what the B-tension did. It was very amusing to watch them try adjust a RD with the guide pulley bouncing up and down on the cassette teeth - awesome!
