longer cranks?

Yo everyone,

Where can I get longer cranks for my uni? (it’s a semcycle)

Bike cranks would work for one side of the uni, but I can’t just use two left
cranks because the pedal would unscrew itself. Do I use a right crank without
any sprockets? I don’t think so I thought I’d ask the experts.

Help me because I’m going to die if I can’t put more braking torque when trying
suicide downhills. (in public in a park with a big audience)

Thanks in advance

Re: longer cranks?

If you want to use road bike cranks on a uni you can get cranks designed for a
tandem bike. Use the right crank from the captain set and the left crank from
the stoker set. You just need to explain to the bike shop why you need them to
order the cranks that way.

If you use tandem cranks you won’t have to mess with grinding away a spider or
helicoiling the right crank.

If you want to splurge you can get Odyssey Black Widow Euro BMX cranks. They
have a square spindle and a removable spider. These cranks are $90 US at BMX
mail order places like http://www.danscomp.com/

(it’s a semcycle) Bike cranks would work for one side of the uni, but I can’t
just use two left cranks because the pedal would unscrew itself. (snip) Hey
Doug; Your local bike store can probably order 170mm or 175mm alloy right cranks
that are used in the rear position of a tandom. The finish might not match your
left crank, but they won’t have a spider. You might also check out the Telford
home page at: (www.sports-psych.com/muni/index.htm). Geoffrey Faraghan lists
various crank lengths as options, which you might be able to order separately
(or better yet, get a Telford along with it!) Finally, John Childs recommended
to me (thanks, John!) the BMX crank "Odyssey Black Widow Euro (aka “Lite”)
available at www.danscomp.com for $90. The spider is removable on these.
Caution: use a 5/32 hex wrench not a 4mm to remove the 3 hex screws fastening
the spider to the crank or you will strip the screw–they are lock-tighted in
there and are hard to get off). These cranks are nice because they are straight
and come in 150mm, 155mm, 160mm, 165mm, and 170mm. I don’t like using 170mm or
175mm cranks (OK, I’m weird–I LIKE the Pashley seat–or should I say dislike it
the least) but my legs are too weak to go uphill with the 152mm I’d been using.
The 160mm I have now are a good compromise. Good luck, Doug

I’m hardly an expert but, …

You really have 3 options

  1. A unicycle specific set of cranks - try the Unicycle Factory (I’m sure the
    address must be at unicycling.org)

  2. As you suggested, get a set of bike cranks and get rid of the spider on the
    right one somehow - try not to generate too much heat doing this as it could
    damage the crank.

  3. Get two left cranks and get one helicoiled with a thread for a right pedal.
    Good bike shops should be able to do this quite easily.

Have fun on those hills!
