Dodici Special - size 53 or 55?!

Hello all at LFGSS,

I just ordered a Dodici Special, size 55. However I am not sure that this is the right size for me. Dodici Cicli shop recommended the Special 53. My height is (184cm) and inseam (33inch). I heard that the Dodici Special frame can run big so it may be good to size down…?

I am planning to use the bike for short/long distance as well as the Velodrome. I am not getting the frame + build purely for track racing.

What do you guys think? Any advice and comments would be much appreciated!
Cheers,

Kacper
