Same set up at 30 kph and Zipp boy is 0.42kph faster and 70 seconds ahead.

I used Bike Calculator with a 165lb rider, 15lb bike, aerobars, no wind or grade. Watts entered to get speed right for zipps and then reduced to find differences for 'average all around wheels'. 15 watts at 50, 4 at 30.
Ok.

An now those time savings as a percent of total elapsed time for each rider?
