Oakleaf,

Thanks for your suggestion- I'm willing to try anything that will help. I did try wetting my hair down last summer and it helps some, although it evaporates in about 5 minutes during summer because the relative humidity here can be as low as 5%. Carrying extra water is already a problem because only a tiny bottle will fit in the 2nd bottle cage.

I really think that if there is better air flow, there will have to be some improvement - but I don't know how much. I had some pretty miserable experiences last summer, and I was only riding about 10-20 miles at that point.
