Italian bike frame sizes.

[Jumpingjackflash]

I have been looking at buying a cinelli supercorsa or colnago master. I am surprised that I have been told I am a 52-54 in the colnago. I am 5’11” am d currently ride a 56 steel bike. What’s size would you recommend in the colnago master or cinelli supercorsa. It is hard to try these frames because they are made to order.

Get the full dimensions and compare to your own bikes or to a similar frame that you can get your hands on to try

Doesn’t sound right to me. I’d have thought a 55 or 56cm top tube.

Here’s a Supercorsa geometry chart:

Colnago sizes are denoted by the seat post length from centre bb to top (just under the saddle collar).

At 5’11” I’d start by looking at the geometry chart for the Master and in particular a 56 or 57cm frame.

Look at the top and head tube lengths, some geo charts will show stack and reach, most of the comparison sites list the Master.

I’m 6’1” and ride a 58cm Master, that has a 56.5cm top and 15cm head tube.

Their Sloping sizes (C64, V3 etc are measured the same and essentially equate to a virtual seat post size of +4cm so a 54s (which I also have) is basically the same geo as a 58cm traditional.

The Master is such an iconic frame and an absolute joy to ride, he’s mine:



Feel free to ask any questions.

At first glance perhaps whoever you were talking to was thinking of sloping sizes as you’d be in that window of a 52s or 54s.

Try comparing on geometrygeeks.bike , it's brilliant for this sort of comparison.

Agree with that view. I’m 6’1” and ride a 59cm Master and a 54cm sloping on a Colnago Air. The top tube on that is 56.5cm, and so sizewise not far adrift from a 58cm on a Master.
OP. I can heartily recommend the Colnago Master
