What the heck are these?


Anyone know? They're on a bike belonging to a friend who stopped by to use my headset press, and she doesn't know either. There's no writing on the crank or the spider, and the rings are old Shimano 8 speed.

One or another of you huge geeks must know...

Yeah. Boone twist. Why I feel the need to comment after the answer has been given is beyond me.

Not a lot of people know this but they are actually machined to give the appearance of being twisted. and not actually twisted
