Hey this may sound like an odd question but I was just wondering if any of you guys with back problems ride a hardtail? Ive got two bad disks and a cracked vertabrea from years of abuse. I have no problems riding my bullit and bb7 downhill or trails etc but I really miss riding a hardtail occasionally. Problem is I have my eye on a sinister ridge and am wondering if I should build one up for trails etc. Should I buy the ridge or stick with the fs. What would you guys do?
