Road bike recommendations

I was told that colnago should fit me as well as they have slightly shorter top tube but i can't figure it out myself looking at the sizing chart. I find it too confusing with a sloping geometry.
I contacted Scherrit, hope he can help.

Use ETT (effective top tube length). Its the equivalent of a horizontal top tube mesurement, and is comparable across different brankds and geometrys.

Take care to also consider the sea tube angle. Eg. A steep seat tube angle will require you to use more saddle set-back. This then increases the overall reach of the bike.

I'm not convinced we all need £££ bike fits. But getting the right sized bike is'nt as simple as glancing at a chart either.

IMHO Any benefit from being able to afford a more flashy frame online. Can quickly be destroyed by having to over adjust the fit of the bike.
