went up to the LBS today. hopped on the 'ol specialized ass-o-meter to get the sit bones measured. got a new saddle (specialized avatar comp gel) that is a MUCH better fit than the one i had been using. lowered the seat height just a tad as well. then...i enjoyed 10 hamstring pain/tightness free miles.
i just love a happy ending. now if i could only figure out how to go faster...
