Part time track racer, riding a 53cm Bianchi Pista Concept until I recently did some damage to the frame . I've been looking at the Dolan Pre Cursa which is very attractive for having very similar ST and TT lengths (within 1cm) and ST angle. However the wheelbase is longer on the Pre Cursa and 1 degree lesser. I wonder if these differences are negligible or can be noticed negatively. I'm very akin to the matching TT and ST lengths of both bikes and have found frames with longer TT than ST have left me with too short a stem for comfort. Any opinions on these frames in particular or similar frames. Thank you in advance!
