Been having issues with left hand numbness, left knee pain behind kneecap and shooting sharp pains up right calf and into hip while riding. Took a day off yesterday and self checked my bike fit. Moved seat up to 165mm measurement from bottom of saddle rail to top of clamp. (Up about 5mm) Came about this height by sitting statically on bike and heel on pedal in fully down position, slight bend in leg. Checked fore and after alignment of saddle, I think the nose was tilted slightly to the left, corrected that. Checked saddle tilt and was perfectly horizontal so left it at that. and moved seat forward on rails by about 4mm. Todays ride was so much better. No shooting pains in right hip, left knee was pretty good just a few moments of discomfort but when I felt these increased my cadence. Numbness in left hand only started at about 50km and I think could have been avoided by shifting hand position more frequently than I did. Now off the bike legs are feeling the best they have felt in days.
