I've got a Dura Ace 7410, 103mm, English threaded bottom bracket for sale. Was purchased NOS about 2 years ago, but not used full time since then. No cyclometer readings to go by...but I estimate, based on my meager riding schedule of about 2-3 1.5 hour rides a week, only about 500 miles on this. Smooth turning, with tens of thousands of miles left in it. Also selling a 7410 crankset to go along with it - look for my other post.
