As bizarre as it sounds, I have a Triton frame designed for multiple wheel sizes. I’m running a 26" and will be switching to a Large Marge when the snow flies. So far no issues from muni riding and commuting other then it looks a little different. I don’t see there being an issue using a KH with similiar plans involved as long as the brakes can be lined up (as discussed).
If I was big on tricks it might get a bit hard to work with.
I thought about this once. I realized that the most expensive portion of the unicycle is the wheel/hub/wheel build/ect. I decided that it is worth the extra money to have two unicycles instead of one and a half, where I have to switch the wheels every time I wanted a different riding style.
It tends to break there if you’re doing street on it. I’ve had a KH24 2007 since then and I bet it up pretty well. I’m a light rider but it does get beat up. I’ve also used a handlebar with it, which adds some extra torque to the frame.
KH24 2009 frame doesn’t fit a 26x3" wheel! That means Kris has lowered the clearance on the KH24 frame also. I mesured my frame from the bearing holders and it’s 13,5". So 1/2" lower than the 07 frames. I didn’t had any smaller tires to try with though. But I think it wouldn’t work anyway.
My take away… Buy a KH26. It will work with a 24 or 26 wheel with the full 3" tire. If I want to add a rim brake it will only work with the 26. More than likely the brake will be for the 26, particularly if it is running a geared hub.
