How to remove crank arm with broken bolt on SRAM Omnium crankset I apparently over-torqued the crank bolt and it made a loud snapping sound. Now the hex wrench just spins freely and so I can neither tighten nor loosen the bolt. How do I remove the (non-drive side) crank arm? Will a replacement bolt, if available, resolve this issue or have I done more damage than that?
I brought this to my local bike shop. They were able to get the external bolt off with a larger hex wrench (the bolt is 8mm). Not sure how they got the inner bolt out--I'll edit with an update when I stop by to pick it up after the replacement part comes in tomorrow.
