Look Ma, No Wires
The new PowerTap wheel is all built. Rim is from an Easton Circuit, spokes are DT Swiss Champion, two cross lacing. Notice the lack of wires or pickup or anything. Just the hub and the head, that's all there is. Really cool. I'm getting really good at building wheels (when I bother to buy the right spokes), as this one took me about 90 minutes start to finish, and I spent a bunch of time unlacing the wrong spokes. The key to building a back wheel is to get it true and dished using just the drive side, and then tune the roundness and tension with the non-drives.
The iPhone camera isn't so great.
Once it was all done I threw the bike on the trainer and briefly dialed into the gearing and cadence I've been using during my LT intervals to see how far off I was. Turns out that I'd been using just slightly less than my "in shape" wattage from last year for my recent workouts, so that's okay.
Greatest dog in the world.
