Review on High-Performance KMC X11SL 11-Speed Bike Chain with 116 Links by James Naylor

I love these chains. I've been riding the Titanium Gold chain for almost five years now. I do about three laps a year and average about 3500 miles per lap. The best thing about them is that they don't stretch! I've never seen one of them miss a shift in their entire lives. The only caveat to not stretching is that you have to track your miles. I once pushed this chain to the limit at about 5000 miles when it finally broke while sprinting uphill. I broke Shimano and rammed red 22 chains while sprinting with less than 1000 miles, but these KMCs are explosion-proof. If you love doing laps, climbing hard, weigh over 175 pounds and need a chain you can count on, then this is the one for you.
