The various KH20 frame sizes.

OK, I found this at:

height of KH20 frame

Question for you all: What do you think is the ideal height for a fork crown above a 19" trials tire? Not tire clearance, but the height measured from the tire to the top surface of the crown, that affects how far above the tire your foot sits for foot-on-frame moves. The spring/summer KH20 had a 45mm height above the tire; Fall 2005 has a 35mm height above the tire. Spring 2006 is currently spec’d as 35mm above the tire, but with a different gusset under the crown to increase tire clearance…

The spring/summer KH20 had a 45mm height above the tire; Fall 2005 has a 35mm height above the tire. Spring 2006 is currently spec’d as 35mm above the tire, but with a different gusset under the crown to increase tire clearance at this height.

My KH20 has 35mm above the tyre so I’d assume that mine is a “Fall 2005” model but apparently my unicycle came in a Nov2004 shipment! Does anyone know if there was an earlier batch that had lower crowns like mine? Perhaps mine is a prototype?

Does anyone else here have the awesome low crown like me? I’ve seen about 5 or 6 other KH20s from friends and videos and I’ve noticed that they’ve all got the high crown.

November down here is spring, up there, it is fall/autumn. So that could possibly be it?
