Sloshing?

A reader asks:

Wondering if you can answer a few questions:

Is there a noticeable "sloshing" when running tubeless with sealant? I'm thinking about running them on my commuter road bike (700x25c)

Have you ridden tubeless in the winter? I'm in Canada and ride through the winter and am worried that the sealant may freeze.

Any help is appreciated...

First, there is no sloshing that I have ever noticed, on road or mountain bikes. The sealant essentially coats the inside of the tire, and doesn't move around much.

As for cold weather concerns, I have covered this issue before:

 Bottom line: Don't worry about it.
