I've got a 110BCD 52T/38T set I used one summer, purchased July 2012 and rode through to October 2012. Was $300 new, selling for a firm $75, buyer pays PP fees and shipping. The short chainstays on my tiny road frame caused too much rub for my liking when cross chained, but I raced an Ironman with them and I feel that they did what they were supposed to do. I'm on QRings now though. Located in Canada, but will ship anywhere.
