A Uni Project

Hi all

I am a recent uni convert and am considering building myself a uni using
‘rockshox’ suspension forks (the type designed for mountain bikes). I
wonder if anyone here has tried anything simalar, and if do do they have
any info or advice they can offer.

Many thanks, sorry my first post here is a request. If anyone has any
circus, juggling, trapeze, acrobatic or stiltwalking questions I would be
happy to help.

Hi David, My cousin and a friend of mine have both experimented with
rockshox suspension forks.

There are a couple of problems with using fork suspension with a unicycle.
As you ride you tend to alternate pressure from the right pedal to
pressure on the left pedal. With non rigid forks this often results in one
side of the shocks compressing and not the other. This causes the wheel to
rub against the shocks and makes the unicycle unrideable. This problem can
be minimised by using high pressure shocks which are quite stiff (and also
more expensive).

The general practice in the unicycling community regards suspension is to
use a combination of the following factors:

Oversize tyre: 2.5"> width tyres with a large depth. For 20" unicycles
Monty trials tyres are good providing about a 3" thick tyre. on a 26" a
Gazziloda is a good choice. The idea is the oversize tyres allow you to
run at a lower pressure with out bottoming out and can provide up to 2"
travel. You usually need an expensive rim as well to accomodate the
larger tyre.

Airseat: more comfortable and a little more forgiving. Miyata and semcycle
seats are fairly easily coverted.

Seat suspension: Not so useful for drops but definately smooths out the
ride. Available with some production unicycles like the Telford.

Feel free to play around with fork suspension but if you want something
useful rather than a gimmick you are probably best off considering
other options.

I have never tried a uni with shocks, but I recall seeing a uni project with the shox on it somewhere on the web. Maybe you have already seen it.

Jeff Lutkus has a page describing how he constructed his own unicycle. I think it is on RIT’s website… You can also get to it through a link at http://wobbling.unicyclist.com along with other links to uni stuff. That might get you more info to get started.

Since John Foss is in his car driving to Idaho for the Muni weekend (or
maybe he is there by now) I don’t know if he will see this soon, so I will
jump in . Dan Hopkins build several Rockshox Mountain unicycles back in
the late 90’s and rode them at the Muni Weekends and NUC’s. I’m sure there
are pictures of a couple of them on Foss’s web site:

http://www.unicycling.com/muni/

Exactly where I can’t say, but I think they are there.

Dan’s machines were interesting to ride and he put a great deal of
research, design and effort into them. However, I seem to remember that he
eventually went back to a rigid frame when the big Gazzalodi tires
appeared. They provide a fair amount of suspension in and of themselves
without the mushy feel of the shock fork.

One interesting thing about Dan’s Munis. The front of his saddles were
radically tipped up so that his body weight rode on the wide part of the
seat. It was really difficult to mount. We all thought is was a bit too
strange, and I don’t know of anyone changed the angle of their saddles.
This year Kris Holm arrived at NUC with his saddles mounted the same way
that Dan had 4 years earlier, for the exact same reason.

All the best,

John Hooten

Details about Dan Hopkins suspension unicycles can be found on his website
at: http://home.earthlink.net/~dmhopkins

Dan told me he quit riding his suspension Muni because the axle broke.
