Suspension Muni

That would be a very HOT ride and hopping w/ that much gravity would be hard :stuck_out_tongue:


haven’t heard back anything about building a uni wheel - I guess after a week I’m not going to. Will just have to wait until they come onto market and see what the options are for replacing the hub.

There doesn’t seem to be any way to adjust those springs, and I doubt that whatever they chose for a bike wheel would work for a uni wheel (since it’s loaded twice as heavily).

Also doesn’t seem like you could have any sag, even if you could adjust the springs, because as the wheel rotates and you move from spring to spring the overall spring rate and loading would change, and you would bounce up and down as you rolled. So for it to work, you would have to be rolling along on fully extended springs - with no way to set the point at which the suspension kicks in.

So even for light duty cross country type usage I’m kinda dubious. For heavy duty muni type riding where you are landing drops and putting a lot of side loading on it, there’s no way those things would be anywhere near as strong as a spoked wheel, so I’m extra dubious.

There could be a method of moving each mount on the rim effectively inc/dec tension (3 screw sliders?). If the stock setting doesn’t work a thicker/thinner and/or longer/shorter spring to the same mount.

You have a point w/ the set sag issue, since it would change depending on the wheel’s possition, but I don’t see how it could be changed w/o effecting tension. Some bouncing I think is prob likely but might not be a big problem as long as it doesn’t start yo-yoing more and more. Also would prob be hard to hop (FS MTBers do it so I think it’d be possible).

I saw this one

there is no unicycle compatible wheel as far as i can tell but it would be worth trying although i suspect running a soft tyre will also do the trick.

That’s what we were all discussing a couple of years ago. I think I’ve now worked out how to adapt one of those to any hub through the use of custom flanges, so just waiting for them to bring out a larger wheel version (ironically they seem to be working on a 26" version, a size which has become obsolete in performance bikes since they started!)

At about 18:15 this guy makes an MTB fork, I believe something similar can be done if a double disk hub is used and brake mounted sprockets. In order to get a brake on it the disc side sprocket should be mounted first then a disk brake spacer, then the disk itself. As long as you change the axle position on the hub and the difference between the sprocket and disk size is good enough it should work.

There is a reason why this specific idea, thread died.

While some other ideas, photos have merit the o p is not in that club.

Just look at the ops, ooops, rendering, it does not compute at all.

Can you invision the axel moving in the frame?Ditto for the rim


And NO doubt it would fail for multiple reasons.

Imho muni sus comes from tire inflation and riders knees, legs.

But one shock with a lock out on The post would certainly function albeit changing seat to pedal spacing of course!

I feel a muni rider benefits from rough terrain inputs helping maintaining balance and speed.

BUT

Suspension on the outside of the rim works, wait we have that via air pressure

Carry on

I wonder if it would work better combined with the

I’m sure that seatposts have been considered before. I guess you have to ask yourself how much travel you really need? Aventon has a nice parallelogram-linkage shock seatpost, but it is too large of a diameter to work with standard unicycle seatposts (which I gather is 25.4 mm = 1 inch?), but, it is the nicest shock seatpost I am aware of.

I think others are Ganopper, Sunlite Parapro 
 but what I can’t figure out is how to attach a unicycle saddle to them. They’re the b*ke two-rail system 


Seems like any shock system for a unicycle would have to be a seatpost shock, or look like the front suspension from a MTB.

This is what you need


That pipe sticking out the front is what I connected my handlebar to. It can also be used to attach a brake to the saddle.

Did you fabricate it yourself? That’s pretty cool!

I did not. I purchased it from a forum member. The saddle mount on my 36er is similar. That one originally came from UDC in ~2007 (I bought it from a different forum member. Thank you, @mindbalance !). So, I think they may have been more common back then. I like them because they allow you adjust the angle of the saddle, as well as the fore/aft positioning. The only negative is that they allow you adjust almost TOO much. It took me a long time to figure out the correct adjustment on my 36er.

that is a lesser known KH piece, i have one and highly recomend it even as a normal riding part. you can find it on google under “Kris Holm rail type adapter” then go to the shopping tab

Thanks!

no problem i love those and i think i might want to get another

Thing about seatpost shocks is, they’re easy enough to engineer into the system (if you’re tall enough), but they don’t really solve the problem. Your feet are still unsuspended. It might make riding on certain types of terrain a little more comfortable, but it can’t help on difficult terrain or drops (probably makes them more difficult).

When riding Muni, the suspesion work is done by your tire and knees. Normally, riders want their handle (saddle handle, T-bar, etc.) as stiff as possible. Having this on a suspended saddle would probably make things harder.

I dont know about you but on long hard trails occaisionaly my arm gets tired and having a little bit of squish to keep my wrist from snapping would be nice, but no more than an inch of travel

So it’s the general idea that suspension would be bad on a unicycle?
