Before getting all wrapped up in 41-style hardware fetishism over the aero-doo-dads for novice racers here's a factoid:
I log my times for a ~4 mile section used for TT intervals.
The 2nd fastest time this year was done on my anti-aero "winter/wet" bike replete w/ full mudguards, 32 hole box section wheels, a 50T "big" ring and a cheerful brass bell.
Fitness, adaptation to the machine and the will to put down a good effort are what are
essential for a fast time.
