Intense arm and wrist pain from riding a DF lead to a diagnosis of some carpal tunnel problems in my right arm and ulnar nerve issues in my left. After considering a pro bike fit, different handlebars/stems/saddle (that hurt too) with encouragement from a 'bent riding friend I work with I sold the DF and bought a 'bent. After re-learning how to ride I loooove it. I'd try a DF again, but am more likely at this point to get a crank forward design for greater comfort. I have designs on a folding bike but that'd just be for short rides.
