20 inch wheels on 26 inch frame

[Thxcuz]

I'm just wondering if anyone has ever done it. I'm sure it looks silly and the crank would have to be addressed but I'm into weird.

I've done 20's on a 24" bike, even with fat tires it required forks from a 27" road bike, and the rear had to be raised about 4". A 26" would require something similar. I've also done 12's on a 20" frame, which required longer forks and shorter cranks.

I guess it depends on the frame. some have a lowered bb which could be a real problem.
