Justified personal beef is fine, but ideally choose one that makes your own life more inconvenient. I'll use myself as an example. Specialized's bikes are often not to my taste, which is whatever, but their history of aggressive litigation, treatment of LBSes (such as the one I work at) and their continued efforts to slowly dismantle brick and mortar businesses leave a bad taste in my mouth. Unfortunately, they also happen to make my favorite saddles, bottle cages, and tires. About once a year, I get in my head and go on a quest to "de-Spesh" my bike, buy a bunch of expensive saddles and tires, and then come back around to the Power Arc Expert and the Butcher/Eliminator. I fully recognize that it's a pointless exercise, but I'll probably do it again next year. Anybody have a similar pointless/inconvenient beef?
