Drink to clear lactate? Nah, lactate is metabolised naturally in various ways.

If your rides are an hour in length, however hard you ride, water is fine. If you want to get into endurance rides you might want to think about on-bike nutrition, but unless you are riding in a starved condition, you can't ride hard enough to exhaust your glycogen reserves in an hour.

And none of this, as far as I am aware, has anything to do with clearing lactate.
