I recently went for a bike fitting session with Paul Hewitt. This was partly in preparation for buying a new bike from him, but also because I wanted to see if I could adjust my riding position to eliminate the lower back pain I often get when riding. As others with a similar problem have reported, Paul suggested I ride in a more stretched out position – basically by moving my seat back and fitting a longer stem. He also strongly advised me to try these changes out on my existing bike before investing in a new bike, as a more stretched position might not work for me. I have now modified my existing bike as he suggested and went for the first long ride on it last weekend. Unfortunately the results were not good and I experienced worse lower back pain than I have done for a considerable period of time Even with my old setup it seemed to be very hit and miss when I would get back pain. One some long rides I would experience virtually no problems, while just a few days later I could get chronic pain on a short ride. So my question is, should I persevere with the setup Paul has recommended to see if things improve after a few more rides? Or should I start making incremental adjustments to his recommended setup to see if this helps – for example by reverting to a shorter stem? Finally not sure if this is relevant, but I found that when I was in the more stretched out position I was having to tilt my head further back in order to see forward, and this felt as if was making my lower back pain worse.
