Shimano Altus Cantilever Brake
Brakes aren't complicated. If you roll, you need to stop. Not only will the Shimano Altus cantilever rim brake slow your roll, it will do it time again and with the precision you demand. It is surprisingly simple in design for how much braking power it produces.
The aluminum design is light and actuates quickly. Pads are easy to change and install. Mounts to your frame in only a few minutes time.
