Any thoughts about the Patterson Transmission two speed chain ring?
I believe so. It's an epicyclic gearbox, the same as a hub gear, and selecting high range gives an overdrive of 1.6:1 according to their info.I'm not sure how it works after looking at the site. Does it work like hub gears at the rear so that front ring turns faster than you're actually pedalling when you shift down?
This is what I had in mind.I like the look of that. Especially as they say it will fit any bike with a standard 68mm bottom bracket.
I've been daydreaming lately about building up a bike with 700c wheels and a Sturmey Archer 8 speed. Combine my spec with this device and it gives a potential gear spread of 30 to 157 gear inches. Perhaps better for a fast recumbent.
Any idea what sort of cost it might be? I don't see that info on the site.The Patterson cable gear change looks easier to use and has a more sleek look to it. I think it might also be cheaper, even when imported from the US.

Thanks for that. I must be blind - never saw that page.http://pattersonbike.com/products-page/
The order page says $299.
The Truvativ HammerschmidtWeird. Didn't the SRAM FSA group already have a two speed epicyclic unit almost identical in spec to this but targeted at the heavy duty off-road crowd?
