Cannondale Sizing... C to C or C to T(9 posts)

Cannondale Sizing... C to C or C to Tfunknuggets

Would a 54cm CAAD 3 be measured C to C or C to T, or do they have a sloping geometry, so it would actually be like a 53? Thanks.

C to T - see geometry diagramPdxMark

I always thought that it was c-c.eyebob

the diagram notwithstanding. To be safe, e-mail tech support at c-dale. They've always been pretty responsive.

Here's my contact...
agree with eyebob, and example whymicha

Sometimes diagrams get drawn and never checked. The Lemond website's diagram three weeks ago showed center-to-top sizing, while the chart below it indicated center-to-center sizing.

cannondale measures c to c. We(the shop I work for) are a dealer
NOT c-c...C-40

Better get out your tape measure. C'dales have always been measured c-t.

There advertised standover height calculates exactly to a c-t measurement.

For example, a 54cm frame has a BB height of 27.3cm. Add 54 times the sine of 74 degrees (51.9cm) and you get the 79.2cm standover height. If the frame was measure c-c, the standover would be at least 1.5cm more.
FWIW, I measured my 54 cm C'dale...Horace Greeley

and it measured 54 cm c-t, and about 52 cm c-c.
whew...thanks guys!funknuggets

The reason that I was asking is that a guy was selling a carbon fork off of a CAAD 3 and indicated that it had been cut to 130mm or so on a 54cm frame. I was really confused, for an alu Fondriest frame (54), the absolute minimum steerer height was in the 150s and that is on the side. So, it now makes more sense. I couldnt fathom any type of geometry that would have made that much of a difference if they were both C to C. This explains most of the difference. Thanks.
