I learned today of an amazing new transmission for bicycles that houses 18 speeds in the bottom bracket (where the pedals connect). It looks like an amazing feat of engineering, and perfect for mountain biking. I’m always wondering what the next big mechanical change in cycling will be. I think this may be it. The only problem is that the frame has to be custom as well. I’m assuming this company will sell complete bikes initially, and perhaps other bike makers will design their frames to accept the gearbox.
