It is an awesome bike for sure. I bought the Large, feel i made a mistake there, after recently riding both medium and my large back to back in some woods recently, i could feel the geometry of the medium suited me (at 5'10) , better. hence the sale. Would consider swapping it for a medium 516 2010 if someone is finding there M too cramped. Failing that, hope to sell the spicy frame and buy a Transition Covert medim frame.
