FS: DA SRM complete 175 39/53 PCV
Do you want to bike with power? Do you want the best at a discount?
I am selling my Dura Ace 7800, SRM Pro crank. Arms are 175mm. Rings are 39/53 tooth. 3-4000 miles, many if not most indoor on the trainer. I am the first/only owner. Battery replaced last year.
Also included: black PCV head unit, just got new battery installed at SRM center in Colorado Springs. (YES! A $50 value! 
AC adapter for charging. Serial and USB cables for downloading. Wiring harness, rear speed sensor = you can use it, and get speed/distance, on your trainer! Includes chainstay mounts, and BB mount for power pickup. 31.8 (oversize) handlebar mount included. I will have to check if I have a 26.0 also.
In short, everything you need to start training with power. Add a polar non-coded strap and you have HR too.
Uses Shimano external type BB/bearings, which you must supply.
All components are in excellent condition.
$2000, shipped CONUS. Located in Denver, CO area. I can send/post pictures if interested.
