I just installed a new set of 180 XT cranks on my Trek 990. I was running a 34T ring on the inside position for proper alignment.
I must admit the best interface between ring and spider was on the outside position, but that comprimised the chainline.
I made it about 3 miles before I sheared 3 of the 4 chainring bolts in a dramatic failure. Most disappointing was the fact that I had bent the spider arms of my new crankset.
Is anyone running these cranks on their SS on the inside position? I have some good thoughts as how to strengthen the interface between the ring/crank, but wondered if anyone here has seen this problem?
Thanks-
