7spd rear, single front ring. I was just tossing in ideas for the 'builder' types.

I don't have a SS bike...yet, I like the idea and have a courier friend who rides one.

My bikes a deconstructed mtb reduced to 7, simple for a mtb I guess.
I intend to go 10-30 rear if possible ( I live close to the North Shore, it's all hills, dirt, moutains.)

Or maybe a 5 rear cluster so I can run a thick fat chain.
