I don’t have a United frame, but have a similar bearings setup with my 24"
Bedford unicycle. It has a bearing cap holder attached from the bottom
that holds the wheel to the frame. Two bolts on each side sandwich the
bearing/hub between the frame and the bearing cap holder.
I mounted a Kenda Kollosal 24x2.6" DH tire. The width clearance is Ok. My
frame has 2.7" wide clearance and the tire, even though it says 2.6"
really measures a little under 2.5". But the height is a problem. When I
have the tire at 25
psi I have 2 millimeters clearance. This is problematic because, even
though I’m light weight, little pebbles get stuck between the tire and
the frame and ping off in a random direction. When I do mud/snow I’ll
need additional clearance. When I inflate the tire to 40 psi it rubs on
So here’s what I’m GOING to try in order to get an additional .5" of
vertical clearance. Get an additional set of bearing cap holders. Place
these below your frame’s bearing holders facing the same direction
(circular side down). You may need to make some spacers to keep the
additonal bearing holders symmetrical front to back. Under these you put
your wheel’s bearings followed by your original bearing cap holders. Get
longer bolts to hold the lot together.
I know I’ll pay a small penalty in additional weight and possibly some
lateral strength, but after riding the 2.6" width (My old tire was a Kenda
2.1" DH) the additional performance of a fatter is well worth it. You
literally glide over sand, and roll over stuff much more smoothly. Hopping
is also much bouncier, like a Monty. But it’s a lot heavier.
I won’t be able to try this idea for 2 weeks because I don’t have
another set of bearing cap holders. If you try it before me please tell
me how it went.
A stronger but more expensive solution would be to get a 28" frame, which
should solve the height problem.
pps The 24x3.0" Gaz is pretty wide and I don’t think you can do this on
your United frame. But it looks great on a 28" Sem. As well, the wider
the tire the heavier it will be. I’ve compromised on the 2.6".
