Bike sizing via Eff TT
Hi guys,
am currently riding a CAAD9 50cm bike with a 52.5cm ETT, and was looking at ordering a Pedal Force frame to build up a new bike.
I would like a TT around 53-53.5cm.
Question is this - these two frames have different geometries, and the RS3 frame with a 53cm TT is actually a size 48, while the ZX3 with a TT of 53.5cm is a size 53. The ZX3 has a taller head tube too, but what I would really like to know is, if I needed a 53cm TT, would a 48cm RS3 fit somewhat like a 53cm ZX3?

Seeing the the ETT length, HT and ST angles are about the same. The main difference would be HT length as you mentioned.
I would say that a 48cm RS3 and a 53cm ZX3 could be adjusted to provide similar fit according to numbers alone.
