I just replace my chain with a Dur-Ace and I'm trying to decide if I just wasted and extra $20. My LBS tells me to replace my chain every 2000 miles regardless of it's ware. I've heard though I should wait until there's 0.75-1% ware (using the Park Tool Chain Tool). So I'm curious:
1) When should I replace my chain?
2) What's the real difference between the Dur-Ace and 105 grade chain?
3) What other brands do people use and why?
