WTB: Rear Trainer Wheel (3)

Just got a new 2014 cervelo P3 in time for winter. I’m not looking to upgrade my wheelset just yet, so I am riding on the wheels that came with it (Mavic Cosmic Elite, which are still pretty good). I’m getting tired of changing the tire to a trainer tire every time I use the trainer, and then back to my good tire when I ride outside on the weekends. Anyone have a rear wheel for sale I can use so I can just swap out the rear wheel instead of changing the tire? Looking for 11 speed 700c. Thanks!
