hi, until now i've mainly done sprint tris on a road bike. i decided that for my bday i was going to buy myself a tri bike and try to work for longer distances. i've been able to ride my new tri bike only a few times and every time i get into the areo position i feel like i'm about to bite it. this is especially true when i'm going downhill. does this feeling ever go away? also, is a brake lever on an aero bar stupid or a decent idea? thanks in advance!
