Shimano XTR FC-M900 Crankset, 170mm, 28-38-48T, 74/110 BCD - Good Condition!. These came on a bike I bought used. I have less than 100 miles on them. I don't know how many they've had in their lifetime. The rings are in great shape and don't look like they have many miles. The rings look very straight. There are no cracks. The threads are in perfect shape. The logos are all worn off and the legs have scratches. The bottom of the legs have scuffs. Will make a great addition to your 1990's vintage build. Let me know if you have any questions.
