it should be noted that this frame is not built up. i am just basing this on throwing a pair of wheels on there and noticing that i dont have the inch to an inch and half between the TT and my crotch. if the difference in top tubes between the 51 and 53 is about 10mm, would this be compensated for by a 110 stem (which i have)? or are there other geometrical figures i should take into account?
