Have a nice set of cranks from one of the best bike component manufacturers out of Italy. Campy has been at the forefront of cycling for decades. This is a set of 172.5 cranks with 53/39 chainrings and an extra 50 large chainring as well. Chainrings are in great shape with minimal wear. Comes with both cranks and two crankbolts. I have not used these. I bought them for a project a while back and just came across them in shed.
