I use the recommended Dumonde Tech free hub grease. I’ve also tried other greases with similar, if not worse results. Grease certainly quiets it down for a while, but it gets back to annoying levels in short order. Like under 100 miles and it’s fully back to full volume. And It’s not just the volume, which isn’t really that loud per se, but the character of the sound that gets to me. It’s a high pitched whine that my riding buddies have likened to an air raid siren.Did you use the same grease...curious about this because I am debating between the Onyx and Hydras, but I do not want a Hub that is too loud.
Would you say the I9 are louder than dt350(36t)?
Looking forward for a review of the new Onyx.
I bought into the “grease quiets the Hydras down to almost silent” BS, and now I’m looking to sell them because the sound drives me nuts.
Anyone want to buy a set of Derby 35i 29” carbon hoops laced to boost centerlock xd hydras? They’re in good shape, the sound just pisses me off now that I’m addicted to silent hubs.
