What’s the deal with the really loud wheels when coasting?

Notices
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

I have a number of wheels with 240S hubs in them with a variety of different ratchets. While there is some difference in noise, it’s not huge between the ratchets but the quality of the noise is different.

I was looking into a building another couple of sets of wheels using 240’s so I looked into the 240 EXPs and played with some wheels with them. They are clearly noisier than the 240S where which is unfortunate.

With the old 240’s you could all but make them silent with a liberal application of the DT grease although it was with increased drag and only for a few hundred miles before the grease moved around. Supposedly it’s similar with the 240EXPs.

Seems like all the hubs are getting noisier now. Maybe it all started with the distinctive “angry bee” Chris King sound or something. Me personally, I’d prefer just about silent hubs but that’s not in the cards,

I’ll likely go with the 240EXP’s just because I like the old 204’s so much, they’re super reliable, and they roll fast and smooth. The new EXPs are are supposedly more reliable and the roll even better although I presume much of that is marketing hype as opposed to actual difference.

Same thing with the old 240s but after a couple of hundred miles they got louder too - done it many times. This won’t last any longer than when the grease moves around inside the hub.

I think the new design is inherently noisier than the old one is what it comes down to. Probably has something to do with one of the ratchets being part of the free hub body so the noise has a more direct path outside of the hub or something.

My only use for loud hubs is for diplomatically letting the guy in front know he needs to roll off.

I have DT Swiss wheels on 2 of my bikes- E1800 and the older R23 model. Both pretty noisy. My FFWD wheels have a DT Swiss 350 hub, that is pretty quiet in comparison.
I don't mind the noise. Drives my wife batty when I ride with her.

Yup. I have a 54t star ratchet in a set of wheels with 240s hubs. Loud AF. I just overhauled it with some fresh Shimano freehub lube, still loud AF.

I don't like loud hubs and dread how loud my new bike will be with its DT Swiss 240 EXP hubs. But I will say that the angry bees of even a moderately loud hub do wonders on a MUP. Better than a bell. Better than "on your left".

I wanted quiet hubs when I raced. That way I got to choose to announce myself or not when I'd bridged up. The longer I wasn't noticed, the longer I had before I was expected to work. I used to take my SunTours apart and lightly grease the pawls. The antithesis of Chris Kings!

We're coasting because we put out 400 Watts and have to wait for losers to get out of our way when we MUP race.

I'm part of the minority here, I like the quieter hubs. When I was ordering new wheels, I chose DT 350s for their lack of hub noise more than their pricing. It's heavier, but I don't race and it's at the center of the wheel, so the weight doesn't matter as much as the rims do in my experience.

A good friend of mine got the I9 Torch hubs and I personally find the noise a bit grating.

He also thinks that hikers on the trails can hear his hubs, but the hub sound doesn't travel through the woods as well as he thinks it does, so the hikers don't hear him anyways. He then complains to me about how hikers should just move over when they hear a mountain biker even though hikers have right of way... I offered to buy him a bell, but he refuses to put on bells on his bikes, so I get to listen to the same complaint over and over again.

Just buy hubs at or above DT 350 quality and you'll get a good, serviceable hub that'll last many years. Hell, even Formula or NovaTec hubs are pretty damn good. You can look up YouTube videos of hub noises, or visit the local bike shops to get an idea of how they sound in person.

Oh yeah. Quiet for me. Loud for the other guys.

Loud hubs are awesome.

I have bikes with loud hubs, and with quiet hubs. There are times when others have louder, or quieter hubs. This displeases me greatly. I am most at ease when the hubs of others sing in concert with mine, at the same level.

Its a level of cycling bliss that most of you poor noobs will never experience.

Throw in the sound of carbon wheels and your got yourself a bike orchestra. Unfortunately, that's not music to my ears.

My Bianchi used to have what seemed to be the loudest freehubs I'd ever heard (Fulcrum Racing 5's). After 13 years, the rear rim started cracking at the spoke holes, so I replaced them with a NEW set of Fulcrums, which are eerily silent. No more using the freehub to announce my presence.

There's always that option, but it will cost you a few watts because of the increased drag.

I hope someone does a study on how much drag noisy hubs make. Then quiet hubs will be all the rage for "free" energy - except then the quiet ones will be the expensive ones.

Might be worth it to stop the madness.

I just picked up a used Canyon Aeroads that has the DT Swiss hubs with the 54 tooth star ratchet upgrade installed. For me, it was too loud for the group rides, cool sound, but too loud for social group rides. Luckily the previous owner included the stock 16 tooth star ratchet and springs. Five minute swap and it now purrs like a kitten! The higher the tooth count on the star ratchet the stronger the springs need to be to ensure it can engage with the shorter ramps....the stronger the springs, the louder the hub! The cool thing about the DT hubs with the star ratchet is I could swap it back in five minutes, no tools needed...slick setup!

Interesting, I would have thought that more teeth means finer mechanism and so quieter operation but I think your explanation holds water.
