*Observe! - Different locks seems to have slightly different sized mounts, ill update the models when able, its designed to be a snug fit and not loose. My brand new lock fits loose but older lock is tight.*

A simplified solution for mounting a Kryptonite u-lock to your bike. 

My original hanger broke and what i found didn't quite match what i had in mind. This should work on most bikes however it might interfere with your leg while biking, on my MTB (with middle hight saddle, to low for optimal performance) i feel it touching my leg, but no biggie.

My Scott has a 31.6mm diameter seat post, my partners Monark 27.2mm. I'm including them and a bigger version with a smaller hole where you can use a negative part to match your bike. 
I recommend cutting it and making a test print, also having it tight is probably better than loose. Cool the seat post and heat the mount if needed!
