In the immortal words of He-Man.
More bits for the new bike have arrived, this time the power meter spider. This fits in place of the direct mount chainring on SRAM Force or Red cranksets, and then you mount a chainring to it. As the name implies, it reports a live reading of how much power I'm putting through the pedals as I ride.
I didn't order the chainring just yet, though. The crankset I ordered came with a chainring (technically you're supposed to be able to get it without, but supply chains), in a rather large 46t size, and I want to get a few rides in to see how the gearing feels before I settle on what size to order to mount up here. There's a 99% chance I'll go with 42t, but there's no sense in being hasty.
