Shimano is argueably the largest producer of bicycle drivetrains in the world, along wth a few lines of disc brakes, wheelsets and pedals. A big corporation with a big heart, they have been disciplined throughout their long history in making environmentally-conscious decisions. Whatever kind of bike you're on, Shimano probably has a component to help you find the next gear.
