One of the front rotors on my 2012 warped after about 2k miles and was replaced under warranty. I bought a set of 2014 take-offs and put them on. After about 2500 miles I could feel the lever pulsating again. I'm going to have to replace it on my dime. Anyone have any luck with an aftermarket alternative? It looks like the stockers are more miss than hit. I spoke to a service manager who said they automatically presume any bike they take on trade will need new rotors.
