I have a set of Real Design Supersonic 60s for sale. Actually the front wheel is an Ultrasonic 60 with the carbon hub and the bladed spokes. The rear wheel is a supersonic 60. They are very true and only have 1 season of racing on them. They have had the decals removed. Thy are 700c and shimano compatible. I need $599 for them. Any takers?? Email me at noscobra@hotmail.com. I only accept paypal.
