I’m sorry for my bad english, i’m italian. I’m going to buy a new tt bike and it will be a cervèlo p3 or a felt da. Ihave a big trouble about the size; these are my dimension
tall 176cm ( 5’77)
inseam 841cm (33.1)
trunk 595cm (23.42)
forearm 345cm (13.58)
My road bike is a 54-55 but someone told me that for a tt bike with an aggressive position(78°) is better have a size in less but i saw that in case of cervello the size will be 51… Is it possible ?? starting with my body measurement is it possible reach the real ttbike size i need maybe looking at the REACH and STACK ??? i have to choose these two factor and after the size ?

please help me because i think that i’m doing confusion

Try the Competitive Cyclist Fit Calculator at competitivecyclist.com. You already have most of your measurements, so you’re halfway there! Email your measurements to them and they will recommend a size for you, as well as component ranges for stem length, crank length, etc. They are also a Cervelo dealer. Good luck!
