I'm doing my first 24 hour race in a few weeks and am wondering which equipment I should use. I have a light wheelset, 60mm aero wheelset, rear disc wheel, normal vented helmet, and an aero helmet. Looking at pictures of the race from previous years, no one is using either aero helmets or disc wheels. I can't really figure out why.
Obviously an aero helmet is going to be hotter than a normal helmet which is a factor in a long race, but iron man triathlons last as long as the first loop in this 24 hour race. So I figure if triathletes can manage with an aero helmet, I should be able to as well especially during the cool morning hours at the start of the race. If its too hot I can switch it out to a normal vented helmet after the first 6 hours/120 miles.
Disc wheels and aero helmets are obviously more of a benefit for when no drafting is being done and drafting is allowed during this race which I'm planning on doing a lot of especially at the start. But racers in team time trials often make use of disc wheels and aero helmets and they're drafting roughly 80% of the time. I've also done many 50+ mile rides with the disc under windy conditions and have never felt that it put me in danger of losing control.
So what do you think? Should I buck convention and use a disc and aero helmet or should I figure that everyone else knows better than I what works and what doesn't and stick with my 60mm rear wheel and vented helmet.
