Hello,

Can I quiet my free hub?

I just got an awesome deal on a brand new 2008 Giant TCR C1.... rides like a rocket, but the only thing I don't like is the loud free hub when coasting. Sounds like when I was a kid and clothes pinned a playing card between by spokes... I know I bought a semi-race bike, and that the sound is functional during a race, but I am not competing against anyone but myself.

I have heard that you can dump oil into the hub? True? How? How much? Any potential consequences that aren't good?

Thanks for your help
Keith

they are loud because of the stregnth of the engagement pawl. It snaps down after pulling over the ledge. If you took a rotary tool and filed down the ledges into smooth ramps you wouldn't get the clicking. Of course you might then also have a dual directional freewheel. A heavier grease might quiet it down a bit but it might also create a dangerous situation. Use only what the manuf. recommends. (not brand, but weight of oil or grease depending on the hub) Those hubs are known for their clicking. You really don't want to do something to impact that as it will impact the function. Just stop coasting.

the shimano's use a diffrent engagement style. Mavic and Hugi are known for their earth shattering loud opperation. Chris King make a humm likened to a bumble bee.

just about every hub is slightly diffrent in sound. most typical is similar to your shimano.

noisy hubs tend to only annoy me on my MTB. On road there is a bit less coasting or if there is i'm doing a fast downhill and am getting other noises anyway. (helmet ect.)

Mavic Noise

By servicing the freehub and adding some gear lube (or even motor oil) you will quiet down the noise to a whisper or even less. I do not think that grease should be used as it might be too thick for the pawls to engage.

Could you recommend another wheelset on par with the Elites that doesn't make all the noise?
a pair of hand laced wheels from a good LBS are hard to go wrong.
ultegra hubs, mavic open pro rim, double butted spokes, alloy nipples
2x up front, 3x in the rear

good solid wheelset nothing fancy but you can ride them longer then you might get out of your frame.

you need to disassemble the hub to lube the freehub. mavic recommends using mineral oil for this, or their race techs have used dumonde tech also. there is a bearing on the outside of the freehub body, but just a phenolic bushing on the inside, which is why you need to lube them frequently. mavic recommends agains using lubes w/ teflon in them, apparently they cause the bushing to swell and drag. be careful when pulling the body off the hub...it's likely the pawls and springs (2 of each, verrrry small springs) will pop out and get lost instantly.

Where do you add the oil? Can this be done without tearing apart the hub?
Mavic has good info on their website addressing freehub body maintenance issues. Good illustrations, etc...

If you cannot find it, Google "Mavic freehub maintenance".

Even if you do need to dismantle the hub, all it takes is a couple hex wrenches.

As posted the info is available in print form, I see a video here

that is very good that shows the dissasembly steps. As some have mentioned I have been using automotive gear oil 80/90 GL5 for a few years, I put just enough in the hub body that it doesn't run out when held horizontal. Doing this service about every 1200 miles keeps the noise down for me. No ill effects in the past 7000 miles

Hope this helps --- Bill

Unlikely fix

It's highly unlikely you could do this well. The ratchet body is hardened tool steel, so would be very hard to grind down. And beyond that, it would very hard to get the many notches ground to a uniform and proper shape. Even as a theoretical, this is a pretty sketchy concept.

This is the weirdest thread...

I've been riding a set of Kysirium Elites for two-and-a-half years now, and I have *A LOT* of things I could complain about (so much so that I finally bought myself a set of Joe Young handbuilt wheels for xmas)

...but noise was never one of my complaints. In fact, my Mavic freehub may be the quietest I've ever encountered. I can roll up on people in total stealth mode. It's eerie how quiet these are.

Why is this a weird thread? I am just used to shimano hubs that are whisper quiet. As I mentioned, I am not a racer, just a guy who liked riding long and fast, and enjoying the countryside without the headache of hearing the clackty, clack of the freehub across whatever percentage of my 3-5 hour ride!

It's just weird because your experience with the sound from Ksyrium Elite hubs is so completely antithetical to mine: as mentioned, "my Mavic freehub may be the quietest I've ever encountered. I can roll up on people in total stealth mode. It's eerie how quiet these are."

I'd be perfectly willing to accept the possibility that my experience is the weird one, & that yours is more typical of Elite users...except I've never heard anyone else complain about excessive noise from Elite hubs.

And also, what else is there to complain about the Mavic elite? It is a light, strong, sturdy wheel... or at least most of the road bike reviewers seem to say so!
Clearly I got a lemon set of Ksyrium Elites. I have had the hubs overhauled twice, the rear wheel completely rebuilt once, they need truing every 3-4 months, and individual spokes tend to twist -- completely negating their "aero" (sic) profile -- with alarming regularity. They require too much maintenance for a two year old wheelset. And I'm a 175lb rider who never takes these off-road or over curbs, so I don't think I'm being inordinately harsh on my wheels. In short, my Ksyrium Elites have not been a particularly "strong" or "sturdy" wheel. And at 1790 grams (these are 2006 Elites, not the apparently lighter 2009 version) I don't think I'd call them particularly "light" either.

To the OP, hope you are getting at least a little help out of this thread. On the issue of spoke "twist" on issue I was able to uncover on a friends bike and later my own was the spoke nipples where they thread into the rim may need a drop of loc-tite, the best type to use is #290, this is a wicking product that is safe for aluminum. Just a drop will do it right where the threads are at the rim. On two rear wheels I have been exposed to we have saw pretty severe spoke loosening in very short time (50 - 200 mile) the loc-tite solved the problem.

If your wheels were rebuilt by somone else, it is very important to hold the spokes (with the plastic holder) while they are tightened.

The freehub is a bit noiser than the shimanos (I have both) but as stated shimano uses more paws with lighter springs.

There is a washer that is very important to get in the right place when reassembling the freehub, it sounds as if you are getting your work done by someone, maybe a second opinion is in order.

Best of luck
