This is a head-to-head (or rather side-by-side) video comparison of two descents of Kings Mountain Road in Woodside. On the left we have a 2009 Tarmac Pro SL road bike with 700c 23mm tires at 100psi and 50-34 x 12-25 gearing. The bike has a PowerTap and an Edge 305. On the right we have 1999 Stumpjumper Pro hard-tail mountain bike with 26" 2.1" knobby tires at 30psi. There is no PowerTap, just the Edge 305 data. The gearing is 44-32-22 by 11-34. The overlays are generated by Bike Telemetry Pro. The road bike route was a pre-ride of the TOC 2010 Stage 3, while the MTB route was the MTB Tour De Peninsula. It was the same rider on both bikes, and the rider was pushing his limits on the descent.
