Used Topline CNC Road Cranks 175 130 BCD Square Taper Polished

175mm crank arm length. 130 BCD chainring sizing. Square taper BB faces and pedal threads in excellent condition. 55 / 42 alloy chainrings have tooth wear and the two chainring bolts closest to the crank arm have difficulty tightening--based on mileage and condition, the chainrings and bolts should probably be replaced.
