My NIMBUS 26 Pull right

1. Could your saddle not pointing straight?
2. Or you tend to apply more pressure to one side of the pedal?
3. Is your wheel well dished?

Funny you mention that. I expierience the same problem in the same
direction but only on my 26" muni. It seems fine on my 20" trials,
figure that one out. So i tried moving my seat to the right a little to
compensate and it seems to help.

I fought the same condition on my 24x3 Yuni (Nimbus) for months. I tried
reversing the frame on the wheelset, switching the tire around on the
rim, aligning the fork legs (at least 3 times). Finally, I gave up and
decided to live with it.
I also have a slight difference (10mm) in leg length and believe that
the wider (Miyata) saddle may have been part of the problem. After I
narrowed the saddle when I did the air conversion, the problem seemed to
be less noticeable. What tire and saddle does your Nimbus have on it?

I had only experienced that condition on my 24x3 Muni also, I haven't
noticed that problem on my 28'r or my Coker (see my other reply for
possible causes)

I had the same problem with my 26 inch MUni. So the MUni became a road
cycle with a super slick tire and I've had no probems since. A few
months after riding the slick, I tried the knobby again. I had the same
problems with it again. So i'm going to stick to a slick on it.

Hope you figure out what's wrong with yours

I've noticed this problem on both my 24"s, my 26" DM and my coker. The
"rotation error" comes and goes. It seemed to be worse at the begining
of a ride, while I was warming up on straight sections. It got to where
I'd notice it and try rotating the seat to compensate, but it only put
more strain on my back. I tried different seats, and different cycles.
Then, when I'd notice myself twisting, I'd do some figure eights, take
some tight turns and then go back to riding straight. -This seemed to
help.

I asked people about this strange phenomenon at several conventions. The
usual answer involed one of my loose screws, or made mention of my
inadequate ability to rationally observe the situation. I even posted
the question here some time ago. The only plausable response I received
mentioned foot position on the pedals. Be sure each foot is positioned
exactly the same -that is each toe/heel is the same distance from the
center of the pedal. Try wearing boots with heels and then make sure the
front of heel is against the pedal on both feet. You may have learned to
uni with one foot skewed, and now you need to retrain, but it's just a
guess.

It could also be a bent pedal axle or misaligned crank. If it's just a
loose screw, tighten it.

Hi newtouni,

Does your Pashley have an obvious ridge running around the centre of the
tyre, this can be either smooth rubber or knobbly?

Pashley's used to always ship with a *terrible* tyre which made riding
straight, especially on tarmac, very challenging / tiring.

For tarmac I find a smoother round profile is ideal, something like the
big apple or coker design (neither of these are 26"😉, Halfords in the UK
used to sell a suitable own brand road tyre.

For off road the Gazza works for a lot of people, and is ridable on
tarmac although the tyre wears very quickly 0n road use. The Gazza
obviously suffers pulling with road camber (due to its width) but much
less than the tyre Pashley used to supply.

All my unicycles started pulling to the left at the same time a couple
of weeks ago. They seem to be perfectly in alignment, but they all
pull to the left in exactly the same way. Obviously they have been
cursed by a powerful voodo cycle-mechanic.

Oddly, the day before my unicycles were cursed I strained a muscle in
the right side of my back. My pedaling became choppy and my right leg
seemed to tire much faster than my left. The cursed unicycles seem to
affect my right leg, making it stiffen and resist the upstroke on every
revolution. It's as if I'm "limping" on the unicycle, or favoring my
right leg.

I'm working on evening out my pedaling force left and right, and
relaxing my right leg, which helps, and sitting up perfectly straight,
which helps even more, but what I really need to do is find that voodo
mechanic and get the curse lifted. D'ya think a bottle of vodka and a
cigar would help?

I have had this problem on my 24x3, but I'd feel myself twisting in the
seat loads to counter it. I think foot placement on the pedals was the
problem tho. When I ride on carpet (the really short haired carpets,
that are almost like felt) whatever uni I was riding would always pull
to one side, to the extent of throwing you off nearly! Interesting ride
tho! I could never line up right for rolling hops and drops etc!

As strange as this may sound, if you have another saddle with a
different center width (viscount or "cheap uni"😉 try it on your Nimbus
and see if you notice any improvement. The narrower saddle may help to
"center" you on the uni. It worked for me 🙂

*I like this uni, but it seems to pull to the right. It is like I
can't get the wheel to stay at a 90 degree angle to the road surface;
like I have to "tilt" ride the thing.

At first I thought it was the knob tire. Now I am not so sure. It
seems to do it in the soft stuff as well, but not as bad. Is it
possible the thing is out of alignment?

Any helpful tips? *

You seem to have a grasp of the possible problems, but here's a 'thread'
(http://tinyurl.com/35lj5) about my similar experience. See U-Turn's
second post therein. Hope it helps.

Good luck,

i sometimes experience the pulling right problem. or for me the problem
exists as having to ride with my torso twisted. it hasn't showed up
lately. the last time was when i switched from a gazz tire to a
fireball. i rode twisted with the fireball for a while and then i
untwisted. the problem went away. then i switched back to the gazz and
i twisted again. then it went away again.

jerryg's comments about turning in figure 8s sounded good to me. i
remember doing something simlilar to help me. the problem is non
existent while riding twisty singletrack.
