I heard that adjustable cranks are really great for technical,
drop-intensive downhill MUniing. Is that true?

The hub interface seems to be weird too. I wonder if you could fit them
at all to any common unicycle. The range is not very large either, at
155 - 180 mm.

For down hill Muni you're going to be doing the same stuff all the
time, so only one length of crank is needed. Also if it's very drop
intensive you need splined cranks. Adjustable cranks are more useful if
for instance, you have to ride several miles on the relative flat to a
Muni trial, so you need short cranks for speed to get there, and long
cranks once you get there so you can climb and descend steep hills etc.

Hmm you may well be right, good point. Also, the cranks are listed as
not for outdoor use, seems a little strange.

You are bidding on a used set of Sunrise Cycleware fitting cranks.

I'm thinking these are for use at a bike shop for "fitting" correct the
cranks to an individual rider.
Just a guess from the context of his description.

They're ugly
And they look fairly heavy too.

Right you are. Good bike shops have fitting machines; a reasonable
mock-up of a bike frame where every dimension is easily adjustable so
they can get a perfect fit for each individual rider before they spend
$3000 on a custom titanium frame. These fit machines look at the
overall best fit of all the components; handlebar width, handlebar stem
length, seat tube angle, seat height, etc.,etc. and (of coarse) crank
arm lenght. That's what these cranks are for. I don't believe they'd
be suitable for any kind of uni riding.

Man, bikes are complex.:eek:

Yet another reason to ride uni.😄

Yup, the cranks are for a fitting bike. A fitting bike looks like
'this' (http://www.bikecult.com/works/archive/serottasc.html).

Also note that the description says:

Quoted message said:

The cranks are sold as is and are not to be ridden outside.

They wouldn't hold up to unicycle use.

Interesting design though. Might give some people some ideas if they
want to make their own adjustable cranks.
