It's $87 because it's about half the weight of your chain and made from parts that wear out quickly so as to convince the idiot that spent $90 on a chain that they have ridden much more than they actually have.
"wow, it only took me 3 months to stretch this one out. I must be riding a lot farther on my weekly 1.5hr ride. I wonder how far I'll ride with next years model. It's supposed to be lighter and cost more. I bet I'll ride so much more I wear it out in TWO months"
