I got a new bike for Father's Day and, following the suggestions of a lot of people, ended up visiting an LBS that specializes in precision fit. It was quite an experience. It cost $200 but lasted over two hours. I can't tell you how comfortable my bike now is.
Anyway, I did a video on it (I work in the media) and thought some of my fellow clydes may like to see it. It's posted on my clydesdalefitness.com blog
