Cranks came loose fix unicycle, уницикл шатуны isis люфт откручиваются

Hello everybody, who like unicycles.
I want to share you one useful trick, to show how to fix very popular issue. I mean about slackness of cranks on modern isis system with 10 ends star shaft. I had this issue on every of my unicycles with isis system, and contrary all my unicycles with square, cotterless shafts was highly reliable. So, it's very possible, that some day you will meet such problem on your unicicle. And it is not a result of loosen screw, wise verse. If you see loosen screw on your right crank it may goues from wore out crank.
Thank you for atantion, Hope you will be safety and enjoyed with your unicycles.

Very nice fix. However, I think with so much yielding of spline bearing surface on crank = many cycles of stress = crank lever breaking soon @ extra hole drilled(not original design) cross section. Be careful doing more jumps.
