I am approaching the 1 year mark on road cycling. The shop I used did a fit to determine my bike size and set the bike up accordingly (2013 Felt Z85). When I began I was told to give it a year before starting to change things, unless a problem arises (sore neck, wrists, butt, etc.) I have had no issues. I have noticed that I am starting to get more flexible. At what point is it time to revisit my bike fit. Currently my stem has 3 spacers in it, I understand that some on here will just tell me to slam it, not what I am asking. Is this a wise course of action, or am I asking for problems? Long time cyclists, what say you?
