    Whippet front mech

    Hi . Can anyone recommend which direct mount front mech to buy? All the ones on chain reaction say specifically for 68-73mm bb shells and 48.8 mm chain lines 68 69 degree seat tube angles.

    I want to run a kcnc k2xc tripple chain set as a double.

    What do I need?

    I am using an XTR high direct mount. If you stick with On Ones recommendations you will be okay:

    High Direct Mount (HDM):
    Any SRAM HDM, 2x10, DUAL PULL
    Low Direct Mount (LDM):
    SRAM XX LDM 2x10 S3 42 TOP PULL- limited to 42T Chainsets

    The following Mechs need a 1mm washer between the HDM plate and the mech:
    Shimano FD-M771-D (XT) 9 speed
    Shimano FD-M661-D (SLX) 9 speed
    Shimano FD-M771-10D (XT) 10 speed
    Shimano FD-M661-10D (SLX) 10 speed

    The following front mechs do not fit
    Low Direct Mount:
    All Shimano LDM
    Eg: Shimano FD-M771-E

    All SRAM LDM excluding XX S3

    Guys, would it be possible to find a way to cover the part on the frame with a metal plate, in order to avoid damages that might be caused by a chain suck? To be honest, I'm a little bit disappointed why the Wippet does not have that metal plate...
    Any aftermarket piece of that metal? Maybe from On-One?

    As an alternative way (I'm just curious for that), would it be possible the lower direct mount mech to put a kind of 'plate', in order to avoid chain suck?
    Why I'm asking this, because, unfortunately, even if I covered my frame with pieces of thick plastic and a lot of zip ties, I got a chain suck (with a perfectly aligned front derailleur!) and my carbon frame has been scratched slightly...

    Today I saw a good example, let's take a look to the new 2013 Scott Genius 700/900's BB92 area:

    OK, it's mounted to ISCG tabs; but, if we are using a HDM derailleur, probably we would still have the possibility to use the LDM to mount a similar thing... Would be REALLY helpful!
