    freewheel clicking volume oscillates while coasting

    Whatup, y'all: I've got Bontrager RaceXLite's on my mountain bike and have a weird clicking sound from the free wheel. The normal ratcheting sound from spinning the rear wheel isn't at constant volume as you would expect. I know some hubs click louder than others as many forums have discussed. But mine actually oscillates in volume from louder to quiet and then repeats back and forth. The faster I spin it, the faster the loud/quiet cycles. One rotation of the wheel equates to one loud/quiet cycle. This is definitely emanating from the freewheel (or freehub?) since I can remove the wheel from the bike and it does the same thing. Can anybody tell me what's going on? Has anyone come across this problem before? Do I have a major problem here? Thanks in advance for your input.

    This is actually quite common, and is not itself a problem, but if you notice any skipping or slipping in the drivetrain, you should probably get a new freehub. Hope this helps..

    DON'T SPEND A DIME on the freewheel YET!!! I had the same problem last year when I pulled my bike off the trainer and it was caused by a barely noticible, slightly bent rear skewer (I normally used a different skewer for the trainer but didn't last year). Anyway ... take a look at the rear wheel hub while off the bike and spinning the wheel. You should notice a very slight wobble between the wheel and the rear cogs. If not, remove the skewer and check it very carefully for non-conformity. Let me know how it turns out for you.

    If I'm not badly mistaken those hubs are made by DT Swiss and the sound it a hallmark of the brand. Someone correct me if I'm wrong.

    I have the same issue with my Bontrager Race Lite wheels. I've noticed when turning the wheel on the maintenance stand the at the cassette assembly will want to try and turn. I thought it was possibly a lubrication issue, but the slightly bent skewer sounds like a possibility......I'll have to check mine out. Funny how it doesn't do it all the time, just occasionally, and then I've noticed if I pedal while, it goes away, but will come back agan.....

    Thanks for your input everyone. Just in case it isn't just something "typical and common", I checked out the bent skewer hypothesis this evening and found it to be straight as can be. I aligned the skewer with a machined straightedge and spun it carefully to find no imperfection. I also checked for any wobble of the cassette; that, too, appears to be sound. But thanks for the ideas, 55-11.

    Tmax1, I believe there are DTSwiss-made Bontragers, but not all of their hubs. I have the link with this info, but left it at work. I can post it tomorrow.

    Now what about this...I remounted the rear wheel and set the chain on the highest gear (smallest cog). I lifted the bike by its saddle and cranked on the pedals to get the rear wheel spinning at high speed. The loud/quiet cycle of the ratcheting volume still remains. However, I noticed something else that wasn't apparent at slower wheel speeds or while I was coasting on the bike...there seems to be a slight weight imbalance of the wheel or tire that causes a slight up and down wobble of the bike. Again, I don't feel this when I'm riding it. The rear tire is tubeless and all I've done to it since the bike arrived in the box last week was pump it up. The wheel is true and, by sight, the tire is properly mounted (I don't see it wobble as I spin the rear wheel).

    Does this help our investigation at all? Again, I appreciate everyone's input. Any news with your Race Lite's, CaptDon?

    Check that the tire is seated properly around the entire rim. This will be immediately noticeable if it's not.

    Could be inconsistent grease coverage on the ratchet mechanism in the freehub.
