I realize that there is already a thread on trials related pains, but I just want comments on a specific pain that I have. I recently started riding a Pure (long) and Team (long). both bikes have Echo bars. Before this I was riding a Zebdi with a Try-All bar and an X-Lite with the flat Monty bar. Shortly after I started riding the new bikes I started having a lot of shoulder pain. My guesses are that it is from riding longer bikes which stretches me out and puts more weight on my arms or that the stiffer bar is causing my arms to get jolted harder when I roll down obstacles or gap to front wheel. It is also possible that the difference in the sweep of the Echo bar is causing problems. Has anyone else had this problem?
