Frame Geometries, anyone know where I can find this?(9 posts)

Frame Geometries, anyone know where I can find this?Tim in Wi

Hello, I am looking for a bike with a 59cm seat tube, and 57cm top tube with relatively long headtube. I think this is an odd size, but its what I need due to my odd body. Can anyone tell me who makes a road frame with this measurements? Thanks!

The 59cm seat tube and 57cm top tube (give or take .5cm) is extremely common. Remember that seat tube angle must be considered along with top tube length to make a valid comparison between brands. Don't know what a "relatively long" head tube means, but some brands (like Litespeed) have increased the head tube length on their frames, to compensate for the use of threadless headsets. Unfortunately, many geometry charts don't list head tube length. Litespeed, Cannondale and Colango all list head tube length. A 59cm Colnago has a 56.9cm top tube, and 16.5cm head tube.

Though my experience is limited, I've never seen or heard of a production road frame that had a top tube shorter than the seat tube. A custom builder could make one, but I think the geometry might be all screwy.

Triathlon and TT bikes have some wacky measurments, but I think they move further from what you're looking for, and generally wouldn't be too comfy for a regular road ride.

Where / how did you figure out you needed a 59cm seat tube and only a 57cm top tube? Are these center to center measurements?

Hmmm, apparently I'm way wrong...Brian B.

Oops, look above, I'm wrong. Sorry. I guess that I've envisioned most bikes with relatively equal tube lengths, then moving further towards the longer top tube, especially with the now popular compact frames...

Colnago for one...mmaggi

There are others, I'm sure.

Bianchi road bikes have shorter top tubes compared to the seat tube. Their 59 cm Veloce and Eros have 57cm top tubes. I don't know about the length of the head tubes. Can you get a longer quill?

Is the Bianchi measurement listed as center to top of the seat tube? So would their measurments actually be relatively "square" using a c-c distance?

you might want to check out calfee bikes at calfeedesign.com. their geometry is pretty dang close to what you were looking for and they have a custom shop as well, their luna pro frames are very reasonably priced and are comparable in price to an oclv but are more reliable, way cooler looking and better riding. they can also build the frame stiffer than stock if you ask them for a nominal fee. it's %99 the ride of a colnago c40 for a third the price.

In what way? Trek's warranty is lifetime, Calfee is *only* 25 years.
