I went on a long (for me ) ride went along the blue ridge parkway from Hendersonville NC to little Switzerland down 221A to Morgantown ,Black mountain then home. The park way had a lot of uneven places so a lot of side to side movement. The back was ok at the end of the ride and also the next day. But now I can't move without Pain pills and muscle relaxers. Anyone use a back brace while riding and if so what kind. I have a tall boy seat with an adjustable back rest .😢
