Hey i’ve noticed something in this movie. How did they do all those jumps and what not with a standard hub and cranks. All though it was a monty, still kept a standard hub system. It’s crazy. But if you look close enough you can tell that they are bent through out nearly the whole movie. Ha. Oh well. Laters
Splined hubs did not exist back when they filmed Universe 1. Dan was also one of the first riders to use a Monty mod trials tire on a unicycle.
Yes, they bent a lot of cranks and broke a lot of axles. It sucks when the equipment wasn’t up to the type of riding they were doing. We’re spoiled now that splined hubs on trials unicycles are common. That was not the case back when Universe 1 was filmed.
Does anyone know exactly what splined means? I’ve asked before, but never gotten an answer…
In one part of that movie, Adam Ryznar (I think) does a huge drop, like ten feet, into some bushes and doesn’t land it. In slow motion, it looks like his ankle completely snaps. What happened there?
HA spoiled
Yeah, i wish i was spoiled. Spoiled are those sucky riders with kris holm. I’m skill using torkers for my riding. It sucks. And kris holm had profile, and so did dan’s 24". So they did have em
But in like 5 years time you do realise we’re all gonna look back on these days with new, stronger, lighter equipment being nice and spoilt and wondering how we coped in this time. Technology changes, and the great thing is because unicycling is fairly new the changes are happening quite rapidly. It’ll slow down one day, no idea when but by then we’ll be doing some pretty crazy stuff on unicycles.
spline
noun
- a) Any of a series of projections on a shaft that fit into slots on a corresponding shaft, enabling both to rotate together. b) The groove or slot for such a projection.
It’s a standard machining technique for securing a shaft inside of another part. In the case of unicycle hubs it is fitting the axle (or spindle) inside the crank.
Park Tool has a page describing how to install splined cranks on a bicycle. The pictures show the spline pattern on the bottom bracket spindle and the matching pattern on the cranks. It’s not the same spline pattern as are used on unicycle hubs, but it gives you the idea.
The alternative way of securing the crank to the hub is the square taper. The square taper does not have a series of projections so it’s not a splined fitting.
Splined hubs are stronger because they are a larger diameter than the square taper hubs. The splined fitting is also more secure than the square taper. Square tapers have a habit of working loose causing the crank to fall off.
what are splines, you ask?
edit: well, John beat me too it while i was making that picture. oh well. he’s more correct than i am, but i got the concept down o.k. no humor this time, though.
oh on the topic of crappy pictures that i make, i saw the one about saddle comfort on unicycle.2ya.com. funny.
Re: HA spoiled
Kris had a DM ATU with the DM splined hub. Kris also had a custom made muni with a custom made hub. The custom hub is the one that broke when he fell off the teeter totter. Kris is the only rider using splined cranks in Universe 1. Back then Kris was not using a Monty style trials uni. He was using the 26 inch DM ATU as his trials uni.
Dan Heaton is riding a Pashley muni with the standard square taper hub that comes with the Pashley.
David Poznanter is riding a square taper hub. The California guys at that time were getting the Semcycle hubs custom re heat treated to make them stronger than the stock Semcycle hubs. David may be riding one of the specially heat treated hubs.
Kris was the only one with a splined hub and with an oversized hub axle.
yeah, i looked at that over and over about 2 years ago too…whats up with that? a serious sprain at least.
On that same note, why did one of the stars of U1 get a mere cameo in U2? (adam ryznar) did he quit? get hurt?
Yeah I was also wondering why all Adam Ryznar did in Universe 2 is grind a bench!
I remember reading in a thread some time last year that he had stopped unicycling for whatever reason.
Andrew
my understanding is that he was involved in another sport at his school and his coach (?) suggested that he stop riding because he was injuring himself a lot on his uni. but i believe he has expressed interest in riding again. but dont forget, there were 2 or 3 shots of him in U2, it was just old footage.
adam dosen’t ride any more.
in universe1 adam’s axle snapped. that drop looks big on film, but it looks insane in person.
mike
when will 125mm profiles be availble?
onetrack, are 125’s the best for street riding?
I think so. smaller cranks add a smoothness to the quick pedaling, faster moves that seperate urban trials from street. I would pay twice as much for a set of 125s if they where available.

Technology will continue to advance more and more quickly. Pretty soon the half-life of your unicycle will be only 3 years before it’s very outdated compared to your competitors. Then even less. Like your computer is outdated a month after you buy it. your digital camera is outdated in maybe 6 months.
really??? Look at unicycles like bikes, only a whole lot simpler. Once you own a uni, and new technology comes along, you can just replace parts. Not the whole uni.
What is there to be advanced??? The only thing that can change is sizes and materials i.e. stronger, lighter, faster parts. I believe that geared hubs will be extensively used in the future, and those will be updated and advanced. Even then, the hub and spokes is all that will need to be replaced.
Technology on bikes is limited to suspension, frame geometry, tubeless tires, shifters, breaks. all of these can be updated to a bike that was made before the tech came along.(not buying a whole new bike).
Mike
please chime in if you think I am wrong.
Mike have u looked into having profile make some 125’s for you or getting some custom ones made at a medal shop or something? Becuase that would be great because im riding 125s on my uni but its cotterless and i want to make the transition to spline but am worried about 145s bein to big.
It is possible to make 125 mm Profile cranks. Greg Moore (gmoore here on the forum) made a custom carbon fiber muni and also made custom 126 mm Profile cranks to go along with it.
See this gallery for pictures.
See this thread for info on the cut down Profile cranks. Scroll down to page two of the thread and look for a post by gmoore.
So if you really want some short Profile cranks you can make your own. I don’t know how much it would cost to have someone to do the machining and welding to make it happen. My guess is that it would be under $100 (that’s just a guesstimate). The tricky part is making sure the pedal hole stays in alignment after it’s welded back on. That’s where a good jig comes in handy.
