Somehow while riding to work, my left pedal unscrewed from my Sugino Messenger crank but not all the way out. Instead, it tilted and jammed like that. I stopped and reached down but it wouldn't budge by hand and I didn't have any big wrenches or anything so I had to ride the rest of the way with my foot doing a weird wobble. Got to work and managed to get the pedal out but not without stripping the threads on the inside of the crank arm. It's just the outer few threads, but the pedal won't go back in. Think my lbs can fix it or is this brand new $150 crank shot?
