anyone know?

Cheap, I've seen fixed hubs (without the brake) go for over 100 quid. Maybe it has been converted to fixed?

u'll need a frame with a cable guide on the left chainstay for it to work
they are such a pain when u wanna change tyres/tubes

You can get jubilee type clips to retrofit it..
I have also now learned that it is relatively easy to convert a standard SA3 into a fixed hub, just by tack welding the pulls.

40 hole? good luck finding a nice rim ;)

I have a 650C tub that came with one of my frames, and it's hub is drilled for 40 spokes, but it's only laced up to a 20h rim.

It might just be that the 20 holes that aren't used are just there for show of course, but you could build it into a completely lethal & totally not recommended under any circumstances whatsoever 20 spoke wheel.

there's ways of lacing them to 36 and 32 hole rims too..

I don't think it's an internally geared hub, I think it's just a drum brake hub. I have no idea if it has lockring threading for fixed use, as you can't see the threads in the photo, so it may be correctly labeled.

Here's a drum brake hub with no internal gears

And here's one with gears:

looks like it's just a drum brake hub with no internal gears.
also, it doesn't look like it's threaded for a lockring... could use it as a suicide hub i guess though.
think they just put 'fixed' on it to draw in the fakengers ;-)

Mavic A719 can still be bought 40H, I got one from BLB (curses) for the Campag rear on the Jackson.
The hub should have a model # on it. Post or google it and all will be revealed.

I watched this hub. The postage put me of.
If you really want to get rid of it, I'll give you a tenner

I think it's the LB as posted above.. will probably be threaded for a lockring.

The spoke holes on the drive side are strange though.. there are 10 slotted holes. It looks like you can feed the spokes head-first through the hole, then pull them into the slots to lock them. I guess its so you can replace borked spokes without removing the sprocket. Kinda clever. Only took another 70 years for a solution to that problem to appear again.
