Hi I was involved in a car accident this past weekend. The back wheel of my mountain bike was wrecked. I had a Cervino (A-class) wheelset on the bike. As the front wheel of the bike is fine, I want to know if it's possible to only buy a back wheel or if you have to buy wheels in a set. Secondly, does anyone know of dealers that sell Cervino wheels in the Western Cape? I'm fairly new to the sport. Any advice will be greatly appreciated. Adios F
