I have been back at riding regularly for 4 years and have done a few centuries, signed up for the National 24 hour challenge last year and got sick the night before, never started. I have a type of arthritis call Ankylosing Spondylitis that effects my lower back, neck, elbows and wrists. Sometimes no issue, sometimes very stiff and painful. My bikes have drop bars, I never have used the drops for more than 2 seconds. Are there any other bars that work for long distance? I am planning on a 200k in June and a 300K in July.
