I am wondering what size people ride who are about 5'11, 56? I have 33 inch inseam.

I'm about the same size, and I can ride a 54 or a 56 Cannondale. I went with the 54 because it was smaller/lighter. Why carry the extra weight if I do not need to? For comparison, I tend to prefer 55cm Bianchis and 56cm Trek. Hope this helps.

I'm 5'11'' as well, I ride a 56cm cannondale. It really depends on how you're built. Leg length and torso length make a big difference.

Cannondales run big

I'm 6'1 and ride 58 Cdale, the top tube is actually 57.5

you'd be 56 most likely, I'm to lazy to check the site and see what the 56 top tube runs but I bet it's 55.5 since they most always run big

thanks i wil try 56cm (56 top tube).

I am 5' 11" and ride a 55cm Six13. Fits absolutely perfect.

I'm 'tween 5'11 and 6' and the 56cm C-dale fits me, but only after I replaced the 110cm stock stem, which was way too short, with a 130mm stem.

I'm 6ft, and ride a size 58 CAAD5 with a 110mm stem. The 58 frame size was recommended to me by the 2 to 3 Cannondale dealers I visited in researching what frame to buy.

Exact same thing here but with a 120mm stem. Ideally, I think that a 57cm frame with a 110mm stem would fit even better in my case.

I'm 6' tall, 55cm Six-13, 100mm stem.

I'm 5'11"-6', 56 cm, 110mm stem.
