I came across some strange TA bolts. At first I thought they were chain suck bolts: bolts that attach the ring to the crank, but stick out to prevent the chain from getting wedged between the crankarm and chainring. The strange thing about there bolts is that the ends are sharp points. I have visions of impaling my ankles on these things in a crash. Maybe they're for something else. Does anyone have a clue? Thanks.
