Quiet hub driver grease options?

Thats usually what happens to them, and the hub tends to go 'fixed'

They need a very light lube (lighter than what you'd use in a DT hub) or else the plastic bushing can howl.

The freehub sound with the Dumonde Tech is significantly quieter. However, after a couple of hundred miles, the sound is back to "normal" loud -- similar to DT Swiss grease. But I do enjoy the silence while it lasts.

That's great to hear, especially since EXP hubs only have one spring instead of two pushing the ratchet through the grease to engage. Presumably it's a stronger spring, but this is a helpful data point. Thanks!

I appreciate that clarification Greg! And good to know about that bitex are somewhat noisy

Yes vespers are tempting... a bit hard to justify, But the custom color options are hot. A couple sets left on Colorado Cyclist right now, down to $430 for a pair

Another fan of Dumonde Tech Pro X freehub grease.
