Up for sale is a genuine Sturmey Archer 23-Tooth (23T) Rear Sprocket. This is a highly specialized cog designed exclusively for Sturmey Archer 8-speed internal gear hubs. It features the unique, large-diameter internal spline interface required for these specific hub drivers.
Because Sturmey Archer 8-speed hubs feature a 1:1 direct drive in 1st gear (and step up from there), running a larger rear cog like this 23T is essential to achieve comfortable, practical gear inches on standard commuter and touring bikes.
