Anyone else suffer from lower back pain? what did you o to fix it? I can comfortably ride about 30-35 miles, but start to get lower back pain around that mark, and by 40-50 miles its agony (depending how many hills I ride!) ! I ride a mixture of hoods and drops to mix up body position but every ride around the 30-35 mile mark I start to get lower back pain! Its at the base of my spine, I don't feel like I'm over reaching for the bars or feel cramped, would be interested to see if anyone else suffers from this and what you done to make it better? Hoping to do 100 mile ride this summer by with the back pain its not looking likely!
