man, the moderators edited my title
i just looked at a tape measure, and found out that the 21in top tube is 53cm, which is 1cm too long for me. and the 52cm seat tube might end up being too tall for me...my other trackies are 48 and 50, and they're a bit smallish, but my 50cm roadie (a pinarello) is just
my size. sure, i could make up the extra cm with a shorter stem, and make my seat a little lower, but, it still probably wouldn't feel right. oh well. i've got two wonderful track bikes already, and i can't really see myself parting with either at the moment.
