Re: IGH Shifters & Anti Rotation Washers
I need to check out the latest SA catalog obviously. I was aware of the thumb shifters, top tube mount shifters and others for older SA hubs but for newer higher number of speed hubs, 7 or greater, the current choices are limited to grip type shifters, at least from SRAM and Rohloff. Not sure of SA. I do have an older Sachs 7 speed thumb shifter for the bike that was stolen from me.
Is the SA8(W) available on any complete bikes available in the U.S. yet or is it a strictly DIY choice for the moment? I was not aware of the Jtek offering as it has not been mentioned here, or on Bike Forums so far as I recall.
The Shimano 8 speed is widely available as a OEM installed unit and both the Rohloff and iM9 are also available on complete bikes.
The Shimano's wide availability and popularity appears to be responsible for the development of aftermarket shifters for it. This is helped I suspect by the minimal cable pull required to shift it over the whole gear range compared to SRAM and Rohloff.

> Actually, Sturmey-Archer has for over a century offered a variety of trigger shifters for their 3-, 4- and 5-speed hubs. At times in the past they have offered stem mounted shifters for their 5-speed. For many years now they have offered push-push (Rapidfire-style) shifters for their 3- and 5-speeds. Jtek offers a barcon for the SA8.
