Used DA crankset with 54/42 chainrings. The crankset and BB are almost brand new. Both have been used for 250-300 miles and were purchased two weeks prior to TTT. There are two small visible scuffs, one on the drive side crank arm and the other on the non-drive side. I am the second owner of the chainrings, I received them from a fellow ST'er. I do cannot recall his total mileage on the chainrings but, I have used them for approximately 500 miles. The chainrings are in great shape and have been well taken care of. $325 shipped in the U.S.
