What is this cassette / hanger combination please?

[RobLoasby]

Interesting concept, but quite limiting on choice of gear ratios I would have thought.

Non drive side spokes look incredibly close to the stays as well, must be super narrow dropout spacing.

Interesting about the 8freight! (had a Google of it)
The tube decal makes you say Vitus 788?

Thanks for the replies so far all!

I've had a bottle of wine to help get in French psyche. Sort of helping but it's not enough.

..... but the facts Hercule:
- It's a road racing bike, considering the rest (no rack mounts, mudguards, blah blah).
- The idea of triples on road racing bikes went up to the Big Mig era, and I think he even experimented with them if I recall some reading correctly.
- World Championship bands on the frame. Basically means not shit, and a builder by unwritten protocol who earned them could have them on their products.
- That rear hub, is anodised black, not silver polished. From memory Mavic and Modolo flirted with a similar colour.
- At this time, it was certainly a known problem with rear axle failures with a 6 speed freewheel.
- Date wise, this surely must be something before the Maillard Helicomatic and well before the 7 speed Shimano freehub unless the designer was trying to solve something else*
- That little cable guide also suggest French to me. Motobecane also had similar tight cable runs with skinny rings.
- We don't have a picture of the NDS. I suspect, and think there must be still a QR thing going on.
- Need more wine.

* My own view of French bikes (and largely due to @Guinessisgoodforyou epic thread) is sometimes they have a knack of solving things with very different approaches, and will make an extra step to make it look good too. I don't think any of us could say it looks a crap job, but accept that does not mean it is French either. I'm dumbfounded for the moment, but warming up more to an idea it's related to chain line.

EDIT: Also, wheel dishing was getting a bit too extreme as well. Probably more racers from that sort of time could confirm spoke breakages with what, 126mm OLN ?

Maybe @ferrus - lover of weird, wonderful rear mechs. could share some light on this arrangement.

Here is a more recent version of the same. Lots of pics to show how it works.

IB17: Wild Mandaric 'Standard 21.5' concept runs the cassette outside the frame

Cassette outside the frame? 21.5mm carbon spindle? All new derailleur design? Mandaric's Standard 21.5 concept has it all, and may just be the future.

For some reason i think the bike in the OP actually might be a Motobecane.

A non dished wheel is an advantage, of course. And it makes for a stiffer rear end.

This is an interesting story and no doubt it works along similar lines.

I saw this some time ago; a belt drive outside the frame, so there is no need for a split in the frame.

English Cycles Project: RIGHT | The Spoken

One of the most innovative bikes seen at this year’s NAHBS was this single speed, single-sided road bike by Oregon’s Rob English. Already known for his prodigious frame designs and creative details, this green machine, which also features hand-painted artwork by Geoff Mcfetridge, surely must...
