It was 81 here today which is a little chilly after 90+ since summer began.

Did a short post work ride and was befuddled by the numbers. At an average heart rate right at 75%, my average speed (moving) was 18.1 which is very fast for this ride which I have done hundreds of times. I have noticed my speed is up with the new bike - especially after getting the seatpost with the required set back. Can a more aero position add .7 mph? Cooler temps = lower heart rate? I don't think so. I wasn't riding totally upright with a parachute before. I haven't gotten any stronger.
