2450 miles before 5% worn, which is good for me. (average is 1700 mi). Connex link is super easy to engage and disengage. On the con side, no matter how much I lubed the chain, or what lube I used, it started squeaking about 40 miles into a 60-100 mile ride. MOST annoying. I went back to SRAM PC-971...less than half the price and only a little shorter life.
Was this a gift?:
Bottom Line No, I would not recommend this to a friend
