as an offshoot to the pretentious hubs thread...
why are some rear hubs so noisy? it seems to be mainly marins in the group i ride with. so clicky clakky! the reast of use are so much quieter
what gives?
The noisy ones are usually due to the rotor body that the cassette sits on being a hollow tube with nowt but a bearing at each end inside. It tends to act as an echo chamber, amplifying the noise of the freewheel mechanism. Quiet ones are usually a Shimano freehub type affair with all the freewheel mechanism squeezed inside the tube instead of on the inner end.
cause noizey hubs r 4 attentionwhores innit.
I run Pro IIs on a Cove Stiffee, Meta 5.5 and a Morewood Izimu DH bike
The Cove is always much louder than the Meta 5.5 and the Morewood is somewhere in-between, I figured it was the frame amplifying it, maybe the swingarms on the full-sussers damping the vibration from the hub?
The volume seems about the same on the cove even when I fit the wheel from the Meta 5.5, which seems to rule out one hub being randomly loud as hell.
what EIASF said...
Noisy freehubs can usually be made quieter with a liberal amount of grease applied to the pawls of the freehub.
Before I read what superdan said I'd have guessed big, boxy swingarms might amplify it
Maybe Marin just use a clicky brand
It's probably a good thing mechanically though - implies a nice positive engagement ?
I've 2 xt hubs that are almost silent, some older hopes that are quite loud and an old DT that's loudish and weird sound cos it has some funny drive mechanism
Hope Pro2 on an Orange 5 is about the loudest I've heard. That swingarm seems to act like a resonance chamber.

what is this noise you speak of?
DT Swiss on my Nicolai helius FR rear end- not at all ninja stealth like at all. In fact, total rubbish for 'cheeky' trails. The welcoming posse is warned ages before my arrival.
