How hard is it to break a hub

Gpickett00 · 2004-04-14T23:53:19+00:00

How hard is it to break a hub on a cheap unicycle. I know how easy it is to taco wheels and bend cranks on my 24" Sun, but i was wondering how hard it is to break a hub. Im not trying to break it on purpose, but wondering how durable they are. Ive bent/tacoed my rim 4 times and after truing it each time it breaks faster. So Im going to order an Alex DM24 Rim. I hear those are good. If not, any other cheap suggestions? also how wide of a tire can fit on an Alex DM24 Rim? mine is a 24X2.125 -- gpickett00 - Level 3.7 Bicycle is just a short way of saying unicycle with a training wheel.

You're good with that rim/tire combo. The Sun BFR rim is
also good, is a little wider and probably stronger, also
more than twice the price. About the same weight.
When you taco your rim you are damaging it. Truing just
straightens it out; it does not make it stronger.
How did you damage the wheel? You may need to upgrade your
entire wheel, not just the rim.

It doesn't sound like you're taco-ing that rim...I've never
heard of a tacoed rim being trued. They're always, as far as
I know, thrown out.
My cheap hub bent after repeated 3'ish drops. The taco
didn't come till later. And the cranks were the first to go.

I was using a stock rim
I jumped down 2 steps (the floor was the '3rd' step)
I was not properly aligned, so the tire folded off the rim
One side of the axle twisted (the crank was still securely
on the hub, but it was now twisted out of ridable position)
It really doesn't take much to ruin a hub, if the situation
is correct. This is something I did over and over, something
goes wrong, bang...twisted hub.
It is also easy to ruin the threads on a hub, also rendering
useless. That's no better

Sun used mindbendingly weak parts on my 26"er. The rim was
single walled very soft steel. I'm not surprised George's
can be repeatedly coerced back into shape, but I'm sure it
is getting weaker and weaker. I bet the nipple holes are
stretching, among other badness.
Anyway, I busted the hub on my Sun unicycle in about a month
of riding without dropping off anything more than an 8"
curb. The stud that holds the crank nut sheared off. Must
have been made of pot metal.
I recommend replacing the hub now. Either way, new spokes
will be needed (figure $15 or more) to go with the new rim,
and swapping hubs now (additional $20-25) will save the
expense of replacing spokes a second time (and the effort of
rebuilding the wheel again).

I think uni damage depends on the rider and the equip.
combos. I've bent my fair share of steel cotterless cranks,
but I've never broken the stock hub on my crappy united rip-
off. But, on my old muni the right taper was beginning to
deform and rotate, so that the cranks weren't parallell.
That was a suzue. Still, I've never had any catastrophic
damage to any of my unis, although my original uni wheel is
no longer tru-able, because of the multiple dents in the
rim. Otherwise, with some new cranks, the thing'd be fine.
I've only taco'd one wheel, and it was a cheap savage that
someone wanted broken. I jumped 14-18" off a stage and
turned 90 degrees and slammed all my weight into the pedals.
The rim taco'd, and the crank was severely bent. Hub was
fine, though.
Sin rhynolite rims are great. I don't know about the DM-
24, but the rhynolite has resisted tacoing, and instead my
tire has just sheared off, but that was just because it
was a 3.0.
