About to order a couple of road bikes bu need to know size to get..

Is there a guide or a site that can work out the right size frame for any given measurements... i.e inside leg, height, arm length etc..

One bike is for the missus so its important i get the right size.

BTW the bikes are Cube GTC's and i cannot find a sizing chart on their site.

Ribble also have a handy guide.

There's also a formula where you measure your inside leg measurement and multiply it by a number like 0.6 (check this)

I used this to size my Cube before finding a dealer and having a sit on one:

Cube sizing is a bit different to others (58 frame has 56 top tube) - use the measurements from the guide to compare to the geometry.

What frame size did you go for? and whats you height/inside leg.

I did notice against a tarmac/madone the cube was indeed about 20mm shorter.

Id there any reason for this?

Oh and are you happy with your cube?
