    Using 5600/105 10s Brifters with a Mid cage MTB rear mech, Compatable/Possible

    Hi All,
    I want to Set up my 5600 105 bike in the same way us can get a WlFil SRAM Apex set up, eg 50/34 up front with up to a 11-32 out back. I have issues getting up steep grades, as long as I can keep spinning I am OK, but I get really choppy when it get really steep. On my commute I have a really nasty climb not all that long, but it has 2 steps and half way up the second i blow, and if i try and push through the legs go an I'm in trouble to the next 5 to 7 kms till i get to work, especially as to all that far latter I have a second climb not as steep but around the same length.

    Now before everyone says, get Apex, $$$ wont allow that to happen in the short term. So my thought is to get a Deore/SLX/XT 10 speed rear mech and use that with what i already have in the short term similar to what we see David Millar is using in the below link:

    David Millarís XX equipped Cervelo S3 Giro 2011 | theroaddiaries

    I would grateful for any responses and love to hear from anyone that may already be playing with something like this set-up.

    or

    This is the Mid cage 105 mech, This according to the specs. will work with a compact and up to a 32 cass

    So the option is this or a RD-M675-SGS

    this has been covered many times. as ted posted you have to use a 9spd mtb derailleur. the new 10spd dyna-sys derailleurs don't work w/ 10spd road shifters. any 9spd shimano mtb derailleur will work.

    Supposedly, according to Shimano... 5700A RD with its 30T max cassette cog... can be adjusted to work with 32T cassette

    that will probably work on a lot of bikes, but it will be dependent on the length of the derailleur hanger. shorter hangers won't work, longer ones will, making it a trial-and-error kinda thing. that said, shimano tends to be quite 'careful' w/ the spec, you can usually get away w/ one step further than they say.

    Should definitely work better than the 28T RD's made for triple cranks....

    Does seem to be cheaper than my M772 Shadow....
