Default Re: A new shift concept for the engineers....

Was tuning my kid's multi-speed bmx yesterday and I'd never noticed before or maybe I just hadn't payed attention to it but the teeth on the cluster aren't straight, they're kind of tilted in and skewed toward the next larger sprocket. Kind of hard to explain, imagine the kerf bends on a circular saw blade but all bent one direction. When I noticed it kind of made sense, seems like it would help the chain bite onto the next sprocket.
