A beautiful December Spring day! Perfect for the first test ride of my other big pre-Black Friday bargain, a pair of Watteam Powerbeat G2 power meters for both road bikes. Installation is complete on the Slice, so I repeated my last TT ride as a test. I can compare the power meter to the estimates from Strava on the previous ride. Both rides were of comparable difficulty, the first with a suffer score of 122 and the second at 94, at 25.4km/h and 26.2km/h average speeds, respectively. The second ride's overall measured power was about 25% higher than the estimate for the first. When I calculate the power from the three hill climbs using "Motion of a Cyclist" I get divergent answers. On northbound Seth Child the power meter is 16% high; on southbound Seth Child it is 29% high; but on the Little Grill hill it's bang-on at 2.7% low! More samples seem to be in order. The total time might seem long because I stopped to talk to a neighbor just before getting home. It really was spring-like: sunny, 62 °F, with light breezes. Accordingly, I wore the uniform of Cannondale bibs and SmartWool jersey, with just no-finger riding gloves.
