iner shifting hub !!!

well guys I found a iner shifting hub made by a bike company that might just work for unicycle!!!

click here

once you go there go down to products click on it. after that click on the product that says speed hub

Brock, nice find, but what will you do about the fact that we need a super beefy axle? I don’t think that hub can handle the forces we will put on it.

then again it just might no?

i’d think that it would work best on a coker or 29er, or just a unicycle in general that would be used mostly for speed, therefore there wouldn’t be as much pressure on the wheel.

well obviously :stuck_out_tongue:

you’d have to be pretty stupid to put that suckah on your trials

Well fine, call me stupid, but who will laugh when I have the world record for fastest 20m rail ride ever?

Honestly, coker riders put lots of force on their hubs, more than you would expect. Also, the hub would be destroyed if you ever fell and it landed on the pedal.

Note: there’s also no space for bearings.

Wouldn’t you need a hub that is not capable of coasting? This thing talks about being able to shift pedaling forwards, backwards or coasting…hmmmm.

You could start off from their concept and build up from there adding the axle, yes, WITH room for bearings.

Casue obviously you can’t use it as is.

But yeah, it would be pretty fragile if you were to smash on the axle or something.

ah well…just a pipe dream

Bevan’s superspeed railride would be a sight indeed.

Rohloff is one of the hubs I examined several years ago. As has been mentioned, something has to be done to make it fixed drive (non-ratcheting) and axle driven rather than chain driven. This hub is driven by the cog shown on the left side of the diagram. The axle is stationary.

Hi Greg and all!

Some years ago I´ve talked to Mr. and Mrs. Rohloff about supporting a
geared hub project but they didn´t show much interest. And to me it
seems impossible to convert a Rohloff bike hub (driven in only one
direction) into a two-way driven uni hub.

i think the rohloff is like 1500 bucks too, shame to get in there with heavy hands.
