Anyone know of any DA 10spd compatible chains that will last longer. The guys at the LBS said the Dura Ace ones should last approx 1500 miles, so at least I got that out of it. I take good care of my drive chain and don't cross gears or do any other things that would cause pre-mature chain wear.
Sounds pretty abnormal to me. I just replaced my DA 10 speed chain (I run full DA gruppo) with about 5000 (hard, fast) miles. It was just past the .75 on the Park tool, and my LBS said it had more life in it. I wanted to spare my cassette however. I clean and lube mine after every ride - how do you take care of yours?
