Umm that frame is really tight, because of the size. for starters your fork has a 37.5 rake. this is not so bad given the headtube angle so you could probably go with a 40 rake on the fork and not notice too much of a difference. next you need to get rid of those crappy iro 170 cranks and put on a set of 165 cranks. you will be well on your way with those two changes and the small-ish cages on your pedals. if you need more, buy the small size cages for the pedals. they wont be too bad , i mean how big can your shoe really be with a 50 frame?
