What are the weaknesses of this design?
TT length. with the TT length that seems ideal for my short arms (about 55 cm), toe-clip interference becomes a problem. My solution is a longer TT with a shorter stem, which seems like it'll work fine in theory but I don't have any experience with putting this sort of thing into practice. Maybe it's not a big deal, since we're talking about a cm here.
