Are Zipp hubs loud?
Yup, Zipp freewheels are much louder than Shimano freewheels. Actually, almost every freewheel in louder than Shimano……
Why are some Freehubs loud?
Loudness in the freehub/freebody is usually due to the very light oil used to lubricate the inner parts. Thicker oil can be used to lessen the noise and even grease in some cases, but it’s high viscosity is pointed at for not being so efficient.
Why do Freehubs make noise?
When the freehub body is driven in the opposite direction, the pawls can’t engage with the teeth of the drive ring, so it is able to spin freely. The pawls click up and down over the teeth, which is what produces the buzz of the freehub.
