I am a huge fan of Cytomax. It is great on the bike & I think makes a super recovery drink. I can really feel the difference when I drink 16 to 24 oz of it after a ride (in addition to some protein - real food; Cheeseburger, Fish, something). I also use Gu Packets, Clif Shots & homemade trailmix. I like bananas too, but rarely carry them on the bike.
