Strange how the little adjustments or changes to the relationship of seat, bars and stem can effect the way we ride and could injure us. I got my seat height off a bit high when I pulled the post to clean and apply CF paste to it. I reinserted it a little high, probably about 2cm, and promptly had a painful time with my left knee and a few days of the bicycle while it healed up. Did a complete check on all the fit settings while I was off and found the seat height changed. Felt really dumb and pained because I didn't check things after maintenance. Kind of like the carpenters warning to the apprentice, measure twice and cut once.
