26" and a 700C

Would it be possible to use a 26" wheel in the back and a 700C wheel in teh front, assuming both wheels fit and you could get brakes to fit both?
or would something kooky happen

One wheel size is significantly smaller than the other. Think about it.

Something kooky would happen, you would have a bike with two different sized tires. It's possible, Trek has their 69ers, and Cannondale used to make a mountain bike with a 24 inch rear wheel. It's just not a good idea unless the frame was built for it.

my first thought is cranks scraping the ground, if not all the time turning would be a *****

Not terribly unusual, called a 96er in mountain biking (or 69er if you like it sexier). Check out this forum

Whether the wheels wind up different sizes would depend on the tires. If you had 2.2 inch in back and a 25mm in front, the wheels would have nearly the same diameter, but that would be kind of silly.

what would happen with the rear smaller, well, crank would lower, seat angle slackens, handlebars move up and back in relation to the cranks, head tube angle decreases, trail increases. So it changes the fit and handling of the bike in a lot of ways.

I've done it when I had a flat front on a mountain bike. One of the hard things to remember is not apply the front brakes as the calipers go into the spokes. You instinctively want to apply the brakes.

The higher rake would give greater hight speed stability but unfortunately more difficulty and extra wheel flop at low speeds, though for that slight difference in diameter it is mild and liveable.

I think you would have difficulty putting a mountain bike wheel on a 700c road bike due chainstay width, but if you were talking about a 650c then it would fit on the 700c bike.

i was thinking of doing this to a cruiser, so the extra rake/seat tube angle doesnt really scare me that much :S
