Is there a regulation on fender size for racing? I ask because I would think you'd want a little more coverage over the top of your front wheel. As is, it's sticking kinda far up, but the top of your tire is moving twice as fast as you are. I read a report on someone taking a bicycle in a wind tunnel with an extendable fender. Slidding it forward reduced drag from a 32mm wide tire going maybe 20mph. Imagine what it would do for a 100mm wide tire going 100mph!
