Freehub question
This is really a silly question but I'll ask anyway. I have an old LX M550 7sp hub on my commuter that I'm going to replace with a 10sp LX T670 hub so I can use the smallest cog. The wheel itself is a relatively new build from this year that doesn't have many miles on it yet. I'm otherwise happy with the wheel as it is really, using 9 cogs of the 10 cog cassette and a dyna-sys 10sp setup. It all works just as Sheldon Brown says it will. The new hub will take the extra cog, and add a little more dish to the wheel to accommodate it. I could have swapped freehub bodies, but the hub was only a little more money than just the body, and then I'd have to readjust the spacing anyway. I'm doing this myself, so there is no other cost. Wheelbuilding is fun to do, and you really appreciate the results.
So here's the question. My current wheel is dead silent when coasting. Will my new T670 hub be as silent? (See I said it was silly.)
