Why do some high end component sets make a clicking sound when coasting?

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Why do some high end component sets make a clicking sound when coasting?

Hi ya'll! I was out on a ride today and passed a specialized s-works Tarmac sl3 while it was coasting, and I noticed (as I have in the past) that when coasting, the hub makes a drastically louder and distinctive clicking sound than most bikes. I have heard this on a variety of other high end cycles and I've always wondered why they do this? Is this an engineering side effect? Or perhaps it just distinguishes itself from other comp sets like an exhaust note on a ferarri... Im just wondering and was hoping someone could alleviate my curiosity. Thanks!

If I could hazard a guess it's because the pawls in the freehub are attached to beefier springs for more reliable engagement, but I could be/probably am way off.

Has nothing to do with the bike being high end, its all in the wheels hubs that make this sound.

Similar reasoning to Campy remaking record 11 click loudly I would guess. Mentally computing your equipment is working or did what you told it to.

Someone used to make a near silent freehub (might actually have been back in yon freewheel days) Can't remember the name of it. Some kind of clutch mechanism, IIRC.

It was pretty fancy.

some of it is the number of pawls.

shimano = 2
campagnolo = 3
hugi = 4 (i think)

volume goes up in the same order. all things equal, more pawls=stronger


then you also have hubs like chris king that have a buzzing "ratchet style" mechanism.

so yes, it is a side effect of a particular design. as a result, it also gives brands a distinguishable tone. campagnolo and chris king are both loud, but completely different tones.


cars are the same way. porsche flat 6s, ferrari v-12s, and small block v8s all have a distinguishable noise due to design. ford and chevy v8s even have distinguishable sounds due to firing order. it was not designed for this, it is just a natural side effect.

All bikes are. Rear hubs are noisy.

To clarify, my Allez rear hub is silent. Whether thats good or bad I prefer a quiet rear hub.

Loud hubs show other riders that you're a ******.

A nice side effect of my Chris King hub is mostly I don't have to yell "on your left" as I pass, they usually hear my hub first.

My hub is extremely quiet...I want a louder one. But I really like that distinct sound, especially when in a Criterium or a large group of riders enters a corner.

It's an alarm. It means you should be pedaling.

Actually, monocoque frames amplify any noise on the bike.

My Phil Wood hub was quite loud until I put a bit more than the recommended load of grease in it the last time I serviced it. I doubt that will harm it and I kind of like silent coasting. I suppose that could mean I have introduced more drag into the system, but no more than my famine insurance system (gut) causes.

My 2005 Allez Elite is quite (Shimano 105 hub).
The Deda hub on my Paramount is noisy.
I like it quite.

Ding, ding, ding! Winner.

You can quiet any hub this way.

Back in the day of 6 spd freewheels for my racing wheels I used sewing machine oil to get the lowest resistance possible. The freewheel was noticeable louder and the sound itself was different. In winter I'd load up my freewheels with grease (against road salt) and lo and behold, dead silent freewheels.

Rocket surgery it ain't.

Not necessarily for long... I packed my cassette body chock-full of grease, and it was quiet for a while, but before long the noise mostly came back as the grease bedded in...

Maybe I just need to squeeze more in there...
