Sturmey Archer Rear Sprocket Sheared

buddha

I had the 3 inner/splined teeth on the rear sprocket shear off today (sturmey Archer 5spd hub). Okay, I was "giving it some", in top gear, on an incline. But these things must be made of mashed potato !
Lucky I was seated at the time or I'd be speaking a few octaves higher :shock:

Is this a 'common' occurance? The sprocket is a genuine Sturmey Archer part, about 8 months old and around 6000 miles. Are there stronger sprockets out there?

Thanks
