I have 2 questions...
1. I am looking for some aero bars to add to my road bike. I have only done sprint tris in the past (have 3 more coming up in series this summer), but may one day train for longer distance. I have been told that even at the shorter sprint distance, aero bars would be beneficial. Any thoughts and most importantly, any suggestions on specific ones?

2. I do not consider myself vain; however, when looking at pics taken of me on the bike, I cannot help but notice I look like a mushroom...my helmet is huge. Are there any good helmets with decent ventilation out there to fit smaller heads??

Thanks for the help!
