    Shimano FC-M970 sheering

    Finally getting back on the bike after a long winter. Purchased this crank last March so it is only a year old. I have 300 plus miles on it. Went for a 30 mile on road ride and at mile 28 noticed my right foot getting wobbly. got home and noticed the entire inside of the crank where the pedal goes in was sheered. First what would cause this, second is there anything I can do to fix this, and third would this be a warranty issue? The left pedal is in perfect and no issues. I rode 2 24 hour races with this set up. I have no idea what would have caused this. I can almost slide the pedal into the slot now with out screwing it on to the crank arm.

    Who installed the pedals? Don't know if it's a warranty issue but it is repairable with a helicoil...
