Scott Bike Sizing

[VeloVT]

I have a 2007 Contessa CR1 pro. At the time, the only differences between the Contessa CR1 Pro and the "men's" CR1 Pro were a) pink details and b) shorter cranks and a women's saddle (both of which I replaced, actually). The frame geometry/measurements were identical. My bike also came with 40 cm handlebars on a size XS frame, which you don't usually see in a "real" WSD bike.

The Scott website used to have the tech specs/geometry/sizing for all of the models -- that would be a good place to look.

At a quick glance:

Top tube length:
Contessa CR1 pro in size 54: 54.5 cm
Speedster S40 in Size 52: 53 cm

Seat tube angle:
Contessa CR1 pro, size 54: 74 deg
Speedster S40, size 52: 74.5 deg

Seat tube length (c-c):
Contessa CR1 pro, 54: 48 cm
Speedster S40, 52: 46 cm

Standover height:
Contessa CR1 pro, 54: 77.5
Speedster S40, 52: 75.3 cm


The Contessa CR1 Pro in 54 **is** a bigger bike than the Speedster you have. I didn't compare the 52 to the 52 directly, but it looks like the sizing between the two models is actually pretty similar.
