New hub concept

Docvelo · 2003-02-25T08:00:21+00:00

I just received pictures, from an european engineer, about a new rear hub concept. With this hub, it's possible to remove and/or replace the rear wheel , without touching gear shifters, because the freewheel body remains at it's place on the bike frame, while removing the wheel... I'd like to know your opinion about this new hub. I put pictures on this page : http://docvelo.membres.jexiste.org/nv_moyeu.htm Does the thing deserve some interest ? Any potential ? Thanx for your comments, that will be sent to the designer. J. Ouellet

Can't see much advantage to it.
With the conventional design, you have to release the brake, release the skewer and pull the
derailleur back, and the wheel falls out.
With your design, you have to release the brake, release the skewer, unscrew and remove the skewer,
and then the wheel comes out. That probably takes longer because of having to unscrew the skewer nut
all the way. Definitely slower when replacing the wheel.

I agree and wonder as well about how the bending loads in the axle are handled. From what I can see,
it seems like the axle is actually two pieces so it must depend on the clamping of the QR keep
things together, not a good idea in my mind.
Seems like this design makes things more complicated with no real advantage.
Motor cycles sometimes use a step similar to this and it avoids having to deal with the chain and
the chain case. For a single speed bike or a hub gear bike, this might be nice but in the case of
the hub gear it would make things even more complex.

I don't see the problem that it addresses. A wheel can be removed ane replaced fairly quickly, if
you know what you are doing. Heck, Rae Dawn Chong managed to make a quick wheel change in American
Flyers with only a little training.
I would think that either the integrity of the axle would be suspect (how does it connect together,
anyway?) or the connection would be as time-consuming to deal with as a standard wheel.
Nothing wrong with touching the gear shifters. On the other hand, here you would have to remove the
QR completely. And manage to get the thing uncoupled, and then back again.

These things have been around for ages. Can't remember if I've seen them with cassettes, but I have
a freewheelversion at the office. Only practical use I see is with a travel bike: A flat wheel
without cogs packs a lot easier in a suitcase. /Marten

Cinelli did this decades ago. It was possible to exchange front and rear wheels with their system.

[snip]
Am I interpreting this design correct ? Could I change wheels, without having to change cassettes ?
To me there would be some merit to that in that I would no longer have to be concerned about
variable cassette ware between the wheelsets I have. Currently I have a cassette on one wheelset
with about 8,000 km, another with about 5,000 and another new. I run the same chain on all of them,
which seems ok at this time, but have read it can lead to problems

Hey, Rae Dawn was an exception woman! She was tough with a heart of gold, and she cared for Kevin
Costner when he was stricken with that fatal nose bleed thing. I was touched. That was perhaps the
best cycling film of all times, second only to PeeWee's Big Adventure.
Anyway, the Cinelli failed to catch on back in the old five-speed days when dish was not such an
issue. I really wonder how this iteration would fare with 130mm 9 or 10 speed spacing. The right
flange is even further toward the center of the hub due to the coupling mechanism. It seems to me
that you would have to go with 140mm spacing to make the dish reasonable -- assuming that you could
justify owning this oddity in the first place. -- Jay Beattie.
