I have a fairly new Shimano XT crankset that just started (yesterday) making a ticking sound. Every time the right crank would hit 12:00 and right when I'd apply torque it would make a tick or creak. Then today toward the end of my ride the ticking went from one tick per revolution to multiple and added a sort of woosh noise with it. I had these cranks professionally installed by Speedgoat and I only have about 500 miles on them. Is there something wrong with them? Also, is there any periodic maintenance that needs to be performed?
