130 BCD Rotor 3D SRM with 165 mm crank arms and 24 mm spindles. It needs either a new battery ($200) or can be upgraded to a rechargeable battery ($850). SRM confirms that the unit can be upgraded to PM9 (which comes with added functionalities such as rechargeable battery and bluetooth). The unit presently has 53/39t round Rotor chainrings with a fair amount of service life.

$200 OBO shipped CONUS via PayPal G&S. Willing to ship to other countries if buyer pays difference in shipping cost.

Dura Ace 9000 SRM with 165 mm arms has about 425 hours of usage, with a claimed battery life of 3000 hours. Comes with 53/39t chainrings that still have a lot of service life (the crankset was primarily used indoors, and I primarily used the 39t chainring). The spider is 110 BCD and accepts other chainring combinations such as 52/36t and 50/34t.

$475 OBO shipped CONUS via PayPal G&S. Can sell just the spider and crankarms for $425 OBO shipped. Open to ship to other countries at buyer's expense.
