    Giant Defy Alliance, compact to triple?

    The bike that I am looking at and may get this Summer or Fall is the Giant Defy Alliance as the geometry is what I am looking for- lax head tube, long wheelbase- and in my size, I really like what I see.

    The thing that bothers me is that it not only doesn't come with a triple but it comes with a compact with a braze-on front derailleur. I know I can just install a triple and a braze-on triple front derailleur but how is one to know if I will be able to set up the front derailleur so that I can avoid rubbing the derailleur in my big ring/small cog and my small ring/big cog combinations? IOW, how can you know if the derailleur will be able to move far enough laterally to accommodate the additional width of a triple?

    The base of my concern is that Giant designed this frame to fit a compact, not a triple.

    I wanted to contact Giant but their site gives a pop-up window that says:
    GIANT Bicycles USA
    3587 Old Conejo Rd.
    Newbury Park, CA 91320California
    Phone: For more info, please contact your local Giant
    Fax: authorized bicycle dealers.

    I guess they don't want to be bothered. I kinda wonder what they would do it I snail-mailed them my question.

    I talked to my local dealer, Off Ramp Bicycles in Santa Clara, CA wasn't too confidence-inspiring when I asked them as they gave me a "it depends" answer.

    The Giant Defy (not Alliance) comes with a triple: http://www.giant-bicycles.com/en-US/...ad/2266/32191/

    At any rate, a decent LBS should be able to swap out a compact double for a triple. Or you could get a wider cassette, and thus wind up with the same range as you would with a triple.

    I was looking at the Defy but it has much different geometry, with a very lax 72 deg seat tube angle which would make getting my knee over the pedal spindle, something I want to do, difficult and would limit my selection of saddles and seatposts to those that push me forward quite a bit. I've found that with a 73 deg seat tube angle, I can use pretty much any saddle I want to.

    I also don't want a wider cassette for road rides as I had one on my cross bike and on the road, I hated it and replaced it with a 12-26.

    What I really want is that 73* sta/58 ett/72.5* hta/20cm head tube length and the Defy Alliance frame's got it.
