Which model Bad Boy? If it's the solo fork,be advised that those single sided hubs are brand-specific to C'dale. Getting a new wheelset could get expensive. Also,depending on which model you have,you might be able to mount 26" wheels with knobbies. If they'll fit,MTB knobbies are much wider than anything 700c(non-29er) and you'll have lots of choices.
If you can go with the 26" wheelset,then it'd be worth it to have a second wheelset for the wide winter tires. If they won't fit,then I'd suggest just swapping tires. You only really have to do it twice a year,and it'll save alot of money over a second wheelset.
