Had for 3 days

Comments On Apr 13, 2014:Only had it for 3 days but it has been great for my last 2 rides. It is a pain in the rear getting that master link on with a screwdriver. Be patient and you will get it on.

Great product

Over a year and holding up well.

Comments On Feb 03, 2014:Granted, it is installed on my wifes bike. It does hold up well to the red dirt around Alabama. I would purchase this again for trail riding. I have not used it for racing conditions. Phil

Good Chain, but rusts easy

Comments On Jan 20, 2014:I have at least 40 hard hours on this chain, and it seems to be holding out great. very little stretching. but I've noticed that it gets a light coating of surface rust fast, sometimes overnight. I don't know if it's the type of metal they use, or a lack of added coating, but I've never had a chain do that before. I live in a dry climate and use chain lube before every ride. I've learned to spray a water displacer like WD-40 on the chain after every ride to prevent the rust.

Right price

Comments On Jan 14, 2014:Seems like a good product and well worth the price. I've ridden hard all summer and fall and have had no issues at all.
