Im only 5'9 but have terrible trouble with left wrist pain. Try rotating the lever down more and keep your arms bent as much as possible when riding. Obviously try to change up without the clutch as much as possible. Staying out of town helps.

Other than that it will build up and get stronger but I find my left wrist is always the limiting factor on my range.

Was never a problem on the SVS though. Could do hundreds of miles without a twinge. The problem I find with the sports bikes I moved onto is that the cable layout prevented the levers being rotated down as far as those on the SV. The SV was a much better design in that respect although the position was less extreme too.

You could also buy a powerball but I never had the patience to use it everyday.
