No, it's a new Sugino crankset, and the bottom bracket can't be more than 500 miles old. I tried realigning it, but it just went back to the way that it was after about 30 minutes of riding, and I made sure all of the stack bolts were tight. So I'm starting to think I'm due for a new chain ring. Has anyone had any experience with the Sugino Messenger?
