Need some help. Friend of mine went from a cheapy street unicycle to building an over-the-top heavy duty trail unicycle. Thing is, in fitting a lot of parts together, he wound up with a 28" frame and a 29" tire (tyre for the transAtlantic amongst us). He measured the frame and thought “Hey, that’ll fit!” It sort of fits. He ground out some of the frame to make way for the tire. When the tire was new and still had the little stringy rubber bits on it, they dragged the top edge of the frame. Now, when we ride mud, the frame pretty much scrapes all the mud off the tire as we go. We worried that plain physics would cause some problem when weight was put on it, but that didn’t seem to be an issue.
Now here’s the thing. His skill level makes it difficult to gauge how much the 1) design of the unicycle is inhibiting his improvement 2) the weight of the unicycle might be causing problems, but not the design. 3) His weight (230) or skill level might be the only difficulty and the ride is fine the way it is.
I’m not a teacher, and he and I (and occasionally another person or two) ride at daybreak, so there’s no one there that can say “Hey, you need to improve _____ skill.” or “Hey, your wheel’s clearance is a significant problem.” or whatever else. Most uni-riders are normal as opposed to ‘morning people’, I’ve come to believe. I can rarely talk the local Uni-gurus into joining us.
Frankly, I’m worried he’ll get sort of discouraged with his lack of progress (he falls a lot.) and I’ll be back to riding my sunrise rides with only my dog along.
What can the hotshots advise that I should look for, ask about, measure, tell him to try… etc? Does the description of the wheel sound like a problem, or should we just concentrate on skill level?
