What about putting sunscreen on before you ride, so you don't get tan lines in the first place?

I'm really interested in this thread, because I'm thinking of putting drops on my Kona (I know, more money on the cheap bike....) so I can change hand positions more often. I'm thinking Ritchey BioMax, but haven't decided on a wrap yet. Hadn't thought of bar phat, either.

Keep us posted on what works!
