Hi, title says most of it but I, yesterday, snapped the Crank Axle on my Cannondale Road Bike. YIKES.

This is new territory for me, and I'm not sure what the name or size of pieces I need. I do not know the model or serial number of my bicycle, but I do have the info on the bottom bracket. BC 1.37 68. Whatever that means.

Any help would be greatly appreciated!

Best,

Dale
