Just out of curiosity--those using the Kurt Kinetic, or perhaps other trainers, do you just use the skewer that is on the bike, or, at least in the case of the Kurt Kinetic, the skewer that comes with the trainer?

Also, since I'm thinking of one, what is the lower limit for storing/using the trainer? I would be using it in an unheated garage. The only reason for consideration is to be able to ride/exercise in bad weather and I may be getting carpal tunnel surgery on my left hand in January(means I can't ride the roads for a minimum of 3 weeks).
