Hi,
Can anyone provide me with or tell me where I can easily get the seat tube and top tube measurements for the Ginat Defy range?

I have had various measurements done and as with others I have a longer torso and shorter legs. So, now I got proper measurements my inseam is 28 +6/8 inches so I estimate seat tube 45-48cm which puts me in the small frame category however my reach is closer to 56cm and I need to see where that falls in the Defy range. Given that this is a compact bike I am correct to say that the seat tube height it no big deal and reach is much more important - therefore if a medium works out best does that mean I can still stand without causing any problems!

Thanks.

    2009 Giant Defy geometry is here...

    2010 model looks exactly the same.

    I found the top tube to be 'long' compared to other bikes.

    Top tube length is the important one. Not sure exactly what the reach measurement is you talk about, but IMO unless you're less than ~5'6" then I can't see you needing a small.

    I'm 5'8 and a bit with average geometry and most of my bikes have a ~55cm top tube.
    More problems but still living....

    Thanks for the advice. Having looked again at my measurements and the figures for both the seat tube, standover and top tube suggest that I should at least be trying a Medium for size. Thanks.

    Might not be much help to you but I'm 5'6" and ride a small Defy 1 with a shorter stem than spec.d 90mm instead of 100 but I'm not very flexible!!!

    I'm 5'9 with inside leg of 30 and I used to ride a Giant TCR medium with 100mm stem. I also had a small as a TT bike.

    Hi

    I am 6'3" with a 34" inside leg.I have two Large (55.5) Giant bikes.A TCR Advanced 1 and a Bowery.The 55.5 is equivelant to a 58cm in traditional geometry.The top tube length on the Defy is aprox 10mm shorter than the TCR.My winter bike is a 58 Trek 1000.

    Hope it helps

    Mark.

    I'm 6' 3" with 32 inside leg and have a Giant Defy3 in M/L and it is just right. I tried the large but the top tube was just too long for comfort. The M/L gives a good low touring position good for a lot of miles. Saying that though I'm 39 and have a back suffering from a snowboarding and getting old!
