http://www.georgeonhisbike.com/whelsh... Whelshpool Hill Contour HD Camera and Iphone Cyclemeter App OK this is a good one, broke the downhill recored record on the GT Backwoods bike (15 years old or more set up with 26 inch Continental Gators running at 116 PSI). OK see the video below and checkout the splits on the times below. The average over a 1 km is 79.68 but on my cyclemeter on the bike it shows Max speed of 89 km per hour. That's a record for the bike. I did go back and double check the wheel diameter was correct as sometimes it resets. But all go to the mm.
