im going to buy a new frame this week, or at least put in an order, for one with custom graphics and an integrated seatpost clamp. im riding a 20.5 tt right now and it just feels to small and i think i need a 21". im just afraid it will be to long and ill still be unhappy, im 5'8". also afraid if i get a 20.75" it will still be to small, any body have anything to say before i jump into a 21". maybe something that will save me some heartbreak?
