Anyone info on this?
There's '3 speed' hubs and also '3 speed rotary' hubs?
What's the difference?
Also, anyone know specifics about the Sturmey Archer 'S3X' - 3 speed fixed gear!
cheers

'3 Speed' uses the old school chain and rod through the axle, the rotary hubs use a system like alfine's, nothing protruding from the end of the axle.
S3X is a 5 speed with some stuff taken out to give 3 fixed ratios (direct drive, under drive 25% and under drive 37.5% - we are possibly looking into the idea of a "Peak District Fixie" that would use this hub or the 2 speed kickback hub

Rotary hubs have the cable actuation on the inside of the dropouts (bit like an Alfine) , the ordinary hub works through a fine chain that runs through the end of the axle and so is a bit more exposed.
The fixed gear is pretty heavy because it has been considerably beefed up from the standard 3 speed. I think it's one of those things that look better in theory than in practise. I should know, I bought one and have never fitted it
Just felt it was too heavy to stick on the back of a lightweight fixie.You can however stick a freewheel on it and then you would have a very robust hub for offroad use.

Oh and the S3X can take a screw on freewheel, converting it into a conventional 3 speed should you wuss out of riding fixed

EDIT-(kind of beaten there)

As far as I'm aware its a 3 speed fixie,so no freewheel.
Hence allowing you to do hills that you might not get up normally with a single fixed gear.

As far as I'm aware its a 3 speed fixie,so no freewheel...It's an odd piece of kit. You can screw on an ordinary freewheel - my White Industries on slips on nicely, or you can even use a cassette type cog and have multiples on it. I think there's even room to have a freewheel and a fixed cog, so you could swap from on to the other.
