- We've realized that the team time trial isn't about power; it's about efficiency. In a 15- to 20-minute race, it's hard to increase power output by 5 percent, but increasing efficiency by 10 percent isn't that difficult.

- We've learned that your bike accounts for only 15 to 25 percent of your overall drag; 75 percent of how fast you go is determined by how your body gets in the way of the air.

- Most people don't realize that a nonaero helmet creates four times the drag of a nonaero wheelset. So you can spend two thousand dollars on a wheelset, or spend two hundred on a helmet and be faster.

- How you put your race number on matters more than having an aero wheel.

- On a round-tubed frame, having a bottle on your seat tube is more aerodynamic than not having one at all, and it's much more aero than putting it on the down tube.

- Wearing gloves in a time trial will slow you down more than using a nonaero front wheel.
