1. Time trialing is about efficiency, not just power. You increase efficiency by becoming more aerodynamic. It's much easier to increase your aerodynamic efficiency rather than increasing your power.

2. Your bike accounts for only about 15-20% of overall drag.

3. Approximately 75% of drag is determined by your body's resistance against the air.

4. Aero-bars will save up to two minutes on a 40km/25mile course. Aero-bars are more aero-dynamic than tri-bars.

5. Keep tyres pumped up hard - tubulars should have about 140psi (regular car tyres are pumped to 30psi)

6. A non-aero helmet creates four times the drag of a non-aero wheelset. It is therefore better (and cheaper) to spend money on a TT helmet, rather those tri-spokes and a disc.

7. How the race number is fixed to the bike matters more than having an aero wheelset. Place it low and stretch the jersey so the number is as flat as possible when the rider is in position and so that it does not create a "sail" effect.

8. On a round tubed bike frame, a water bottle on the seat tube is more aero than having no water bottle. It is more aero to put it on the seatpost than on the down tube.

9. Wearing gloves creates more drag than having a non-aero front wheel. Like the helmet - spend money on close fitting, smooth gloves rather than a HED disc...

10. TT booties and a skin suit will only save you seconds, and are not worth the expense unless you are an elite contender.
