Quieting down DT 240s?

It's probably best to use the DT grease and a new application makes them much quieter. When I had a set I'd know it was time to re-lube when they got noisier. They're sooo easy to do.

My current BWW hubs are similar too (on both my mtn and road bikes) - noise means time for more lube.

Anybody have any grease recommendations to make my 240s quieter? How quiet does DT's factory grease make the hub? Bought them used with the 36 point upgrade so I don't have any idea what's in them currently. Any info appreciated. Thanks.

I wouldn't try thicker greases to try and quiet them down, not saying that's what you're doing but just putting that out there right away. The thicker grease may prevent full engagement of the teeth on the star ratchets. I've found just keeping them clean with fresh lube/grease keeps them as quiet as you can get them. I use a light bit of Phil's grease with a couple drops of Tri Flow and that seems to work pretty well. I also have the 36pt star ratchets.

If engagement isn't a big worry for you I would say trade for the 18pt ratchets. The hubs are definitely a bit quieter with fresh lube on the 36pt ratchet, but they are way quieter with the 18t ratchet installed. With the old 18pt I could barely hear the hub over the noise of my tires scrambling on the dirt

I use Phil Wood water proof grease and they quiet down nicely with the 36pt ratchets. Be careful not to put too much as it may prevent the teeth from making full contact with each other.

Grease like Phil Woods or even slick honey is too thick for the ring drives. I use Chris King's Ring Drive Lube - made at their spec and really quiets down noisy hubs without causing drag or engagement issues. All the local shop gurus here in P-town use it. Worked for my DT 340!

Have FUN!

36t "upgrade" on my 240s and I use Phil Wood grease (I have the CK stuff too, hub was still pretty loud). Works, no skipped teeth, drive still looks mint and it's quiet.

Don't go too crazy with the grease, you're just trying to dampen the impact of the teeth engaging not fill the hub with grease.

Thanks for all the input. I ended up cleaning and lightly regreasing the the rings with some low viscosity grease I had available. Definitely better than before but now I really notice the "wahh ...... wahh", once per rev sound that I think comes from slightly uneven spring pressure of the rings. Not much one can do about that I guess.

I've always ridden Shimano hubs so it's taking me a while to get used to hubs you can hear.
