Nashbar branded compact crankset, ISIS, 172.5 mm, 50/34 rings pinned and ramped, used for 30 miles.
This is a cheap alternative to all the other compact cranksets out there, and they work quite well, and are very comparable in weight.
They are in excellent condition, but decided compact cranks were not for me. Pedal threads and splines in perfect condition. Asking $80 + shipping OBO. email me at wilson@cs.wisc.edu.
