since SRAM doesn’t want to keep using the same Reynolds-made rims that Saris used to use for the Powertap wheels, the remaining carbon wheelsets are, for the type of product, dirt cheap – 835.00 USD for a carbon clincher wheelset+poweremeter.
I will admit to having bought a set in December, and then putting the unopened wheel box in a closet. When the trusty HED alloy+powertap wheelset I bought in 2015 finally dies in a couple of years, I’ll use the closeout carbon ones – still cheaper than wheels+crank-based powermeter.
