Bent Monty Cranks

Ben’s Monty alloy cranks lasted about a year but I guess Ben’s a bit bigger this summer than last. He did some dropping off the parade float last weekend and sure enough, he torqued the right crank (he hops right foot back). They’re also starting to strip out a little at the square taper.

I installed them with a hydraulic press last year so they were on pretty tight. But I’m afraid it’s the same with any alloy cranks over time. This is the first time though that I’ve ever seen an alloy crank twisted. They usually snap, don’t they?

Were these the 140s or the 158s, and did he roll out?
