Hi

Have just taken delivery of new xt front mech. It has come with a strange looking plastic tab on it with a lever. This is jutting out from the front of the mech. Have never seen anything like it before.

Cannot see how to take it off, if it does come off, and am not sure what it is for.

Any ideas?

Thanks

    so have you read the instuctions that come with it?

    it is covered.

    I guess you are on about the Pro set block.

  • no instructions, which I guess why it was on offer.

    what is the pro set block?
  • It's probably the alignment spacer for use during installation.

    Normally, I just jam an Allen key into the front mech when aligning the outer cage plate the necessary 2-3mm above the biggest chainring.

    then go and download the manual from shimanos webby.

  • Leave it in place. Adjust the low setting. Remove it then adjust the high setting. Did one last week.

    Its simply to help setup, allows you to set the mech in the right place above the large chainring, once its position, pull it out and whack it somewhere safe for next time you need to replace/move/etc a front mech!
