Where to buy Unicycle parts?

I am chopping the bottom off of my 24" CyclePro frame and making it into a
20" uni. The only new part that it seems like I would need is a new 20" rim
to put on it. I have never actually taken apart my uni and I don’t know how
the bearing, axle, and rim fit together. Can I buy just a regular 20" bike
rim and put it on there? Will it fit? If there is a special unicycle rim,
where can I buy it?

Also, if anyone has an explanation or comments about taking apart the unicycle
and taking off the rim, I would be very appreciative.

Thanks, Josh Lotz glenhillco@iname.com

Re: Where to buy Unicycle parts?

Any 20" bicycle rim will work fine as long as it has the same number of spoke
holes as your unicycle has spokes (probably 28). Here’s what you do:

  1. Remove the frame from the wheel, probably a four bolt operation, like you do
    when you change the tire.

  2. Remove the tire and tube.

  3. Remove all the spokes from your current rim. (Requires a screwdriver or
    spoke wrench.)

  4. Re-lace the wheel with your new (or used) 20" bicycle rim and some new
    spokes. (You’ll need shorter spokes for the 20" tire. Your bike shop can
    probably figure out what length spokes you’ll need.)

  5. True the wheel. I do this with the wheel (no tire) in the frame so I can
    spin it and see which side the tire is closer to. If you don’t want to true
    it yourself, you can probably have the bike shop do it for $10. Or they’d
    probably do the whole conversion for $25 plus parts.

  6. Put a new 20" tire and 20" tube on.

  7. Attach the frame again. You’re done!

You mentioned chopping the bottom of the frame off. Actually, this isn’t totally
necessary in order to get a 20" unicycle. If you change wheels and leave the
frame as-is, it just means there will be 2" of extra clearance betweent the top
of your tire and the frame.

Thanks, but I forgot to mention that the frame is cracked on the bottom. It is
useless as a 24" uni right now. The only way I can salvage the uni is to cut
above the crack and start fresh with a 20" rim.

That does make a difference. I’ll bet it cracked right around the=20 bolt holes.
That’s happened to me on a Zephyr. =20

BUT-- if you have a welder, it wouldn’t be that hard to repair it as=20 a 24".
Here’s what you do: =20

  1. Cut the forks off cleanly (and to equal lengths) right above the=20 bolt
    holes or the crack, whichever extends up the furthest.

  2. Buy yourself an old used set of 10 speed handlebars. The tubing=20 used in
    these is the same diameter as your unicycle frame, and they=20 are of
    similar material. 10 speed handlebars are pretty curvy, but=20 each set also
    has four straight sections. From the two longest of=20 these straight
    sections cut yourself a couple of frame extensions.

  3. Get somebody to weld the extensions to the ends of your nicely=20 trimmed
    frame. =20 (I had one done at a True Value hardware shop for $10 once. But
    now I=20 own a mig welder, so I do it myself.)=20

  4. Drill new holes for the hub bolts to go in. =20

Voila! New unicycle.

Actually, this is the same way I got a 26" Muni and a 27" uni out of a=20 20"
Zephyr and a 24" Zephyr. I just added more frame than I cut off. =20 Then I
could fit the bigger wheels underneath. =20

Just a suggestion.

Chris

Re: Where to buy Unicycle parts?

No, I haven’t had any breakage problems at the weld. (one uni is going on two
years after welding) The weld is close enough to the point of attachment (down
by the hub) that it is not in a high stress area. And actually, the handlebar
material has lasted better right around the bolt holes than the original frame
tubing did.

As for cranks, it depends on where you ride. You’ve probably got 6" cranks on it
right now. Those are decent for some off-road, even with a 26" tire. If you want
more speed (at the sacrifice of some torque), try some 5 inchers. Or if you’re a
definitely off-road guy, 6.75" cranks (standard 170 mm mountain bike cranks,
minus the spider that comes on the right crank) work great. Also, if you go with
aluminum cranks and an aluminum rim, your final product will be lighter than
your original uni, even though it has a bigger tire.

Good luck,

Chris

Great, thanks for the info.

One thing though, has your welding idea been strong enough to withstand normal
uni abuse? I would think that it would be kind of weak where the weld is and
would be prone to breaking off.

Also, if I were to make the uni into a 26", would I need to buy longer cranks?
