And efficiency deference 99.99% users cannot tell at all. BTW, chain IS NOT 100% effcient. :) Tomw, I don’t see point of your idea… iternal gear 2 speed hub is very simple to use.

I have a 1967 F&S Torpedo Duomatic that works as good as it did when it was produced 42 years ago. Everybody is surprised that I run two gears without any cables of any sort to clutter up the look. A few drops of oil into the oil port every few weeks and she runs smooth as butter. I will buy the Sc2 to compare with the original when it comes out. I wonder if it will have an oil port to add oil periodically instead of having to open up the hub? Perhaps it will be a sealed cartridge bearing system like on some other Sturmey hubs? Any more details on this new Sc2 would be welcome. This is very good news!
