How noisy are the hubs?

Hub noise is something that intrigues a lot of people. Why are some hubs super loud, and others almost silent?

The answer is because when the pawls click over the teeth inside the hub, they make a noise. Depending on how many pawls, how many teeth, and how powerful the springing mechanism is to push the pawl outward, will dictate how loud the hubs are when you are coasting.

Our hubs use leaf springs to push each pawl outward. When you are pedaling, each pawl will push against the driver ring and move the wheel forward. When you are coasting, the pawls will click up and down over top of the ramped teeth in the driver ring. Because we are using the leaf springs, we ensure very solid engagement that will not skip or jump when you stomp on the pedals.

The noise level with this system can actually be adjusted slightly. By adding grease to the pawls and driver ring, you will dampen the sound a little. With this you can choose if you want your hub to be attention getting loud, or a stealthy clicking style.  We encourage people to use the NixFrixShun SpeedCoat when servicing their driver ring and pawls.
