After 25 years of racing and now racing Cat 1, this is the best power meter setup I've used. The Quarq integration is clean, light, and incredibly accurate. Shifting is crisp with the 13-tooth delta, and the chainrings are super durable. If you want pro-level performance and data, this is the kit to get.
SRAM Red / Quarq power meters are top notch, I ride outside all year from 32F to 110F. No power spikes, consistently accurate at all temps. The new E1 fits on existing crank, pair with E1 front derailleur to fit all sizes.
