Currently I have three sets of tires for my Cannondale Quick4. My Quick has 26 inch wheels. I have 1.7 knobby tires I use on gravel roads and ratty paths. I have slicks that I have used for faster rides, I can't recall the diameter. I have 1.5 tough tires without much tread for all around use, but they are not the best for loose gravel. I end up wanting to swap out tires frequently. The 1.5s are a bit tough for me to get on. The other two are pretty easy. Sometimes I want to do a swap for a ride but don't because it is somewhat of a production.

What are my options? I am not sophisticated about bikes, even though I am pretty good at changing a tire. If I wanted to buy additional sets of wheels where would I find them? How do I figure what is the appropriate size, beyond the fact that I know that my bike has 26 inch wheels, rather than the 700s that are on the larger sized Quicks. For the rear wheel, would I have to buy a cassette? My bike is a 2011, the 2012 version has the Sunrace CSM668, 11-32, 8-speed on it. Here are the 2011 specs: http://www.bikepedia.com/QuickBike/B...6%22&Type=bike

How do I figure out what to buy? How would swapping out the rear wheel work? And, are they any questions I should have asked but did not ask?

Thanks for any help you can give me.
