Yes and no. There hub does free wheel but it's not a standard design freehub.

It's made up of three bearing on the end of a flanged spring clip(?)

So when you pedal the spring expands into a set of teeth on the hub shell.

Called the "rock and roll" design.

ROLLIN'ROLL

ROLLIN´ROLL - revolutionary clutch, patented by the House of RB Design, has been designed for all kinds of freewheel bicycles. Really revolutionary clutch not resembling a little bit to any of those, controversial "Epoch Making" inventions appearing and disappearing every year but of no use.

With ROLLIN´ROLL you can forget all problems occurring in connection with other freewheel clutch systems. No matter how many pawls the system comprises, might it be even the frontcogged ratchet system, all of them have one common shortage. The pawls and cogs are never operating simultaneously at same moment. Thus every time when only a single pawl is in action, it is likely cause the destruction of the edge either of the cog or the pawl itself. Try tu turn slowly any freewheel hub and listen carefully. You hear the segments to engage one by one consequently, not in the proper way at once all of them. There is no doubt, that the pawls and the cogs respectively often do not mesh correctly, they are simply engaged by the edge of one of the pawls. The edge not being able to resist the extreme stress and faces inevitable destruction.

Try ROLLIN´ROLL (view animation) our patented brand mark product it is going to get rid of above mentioned trouble. We do not use any pawls in our clutch anymore. There are meshing needle rollers working instead. But not like those ones in self-locking "silent clutches" suffering a little detrition cause the clutch to slip.

ROLLIN´ROLL rollers fit into the proper concave flute of the waveguide perfectly. The shape of the flutes has been designed with the aim to enable:

Exact meshing of the needle rollers with the remaining parts of the clutch.

The needle rollers to fit into the proper spot simultaneously and at once, so that the actual stress of engagement is divided equally between them.

The needle rollers to fit in the purposefully shaped concave flutes of the waveguide optimally in order to split the actual stress over the possibly biggest area.

To achieve an extremely short idle course of the clutch.

Our sophisticated solution, the ROLLIN´ROLL freewheel clutch, is not only a solid, but even a long-lasting clutch. We are happy indeed to be able to offer it to those who appreciated. Only they can understand the real value of ROLLIN´ROLL clutch.

My advice stay the hell away.

yer i wouldn't go near them joe, cos the engagements work by a ball bearing being jammed against the inside of the hubshell they tend to explode from the pressure

EDIT: and awnsering your question, yes they are a free hub, they have either 32 or 36 engagements

its also known as the torrington clutch system, they have infinity engagements, they are silent, but recent ones have had a tendency to dying and are sluggish with spongy engagement . but i have an idea which will eradicate these problems and will have a hub made when i have some money kicking about which isn't now.
