Checked out my nitron suspension today with the thought of trying the sport setting, dealer set it to comfort. Hmm, I always suspected the front wasn't quite right .. front left & right were at different settings to each other & different to the rear. (settings can be found in the newer handbooks). you may want to check them.(I live in the NW!!!) I managed to change the fronts by just jacking up the front. had to take the wheels off on the rear.
