I am selling my PowerCranks real cheap
These PowerCranks have less than 20 hours of trainer only riding. I mostly used these to figure out what was wrong with my pedal stroke and then did drills with these to fix the problem. If you have a problem with your pedal stroke these will find it and will make you stronger and more coordinated. They worked for me. For more info see http://www.powercranks.com/ They are still in the box they came in with the original invoice and instruction manual. Tech info:
Spider-110 Compact
ISIS
Length-175
