Kryptonite 1090 Evolution 4 case for bike

I tried to find a proper way to attach my (huge) bike chain Kryptonite 1090 Evolution 4 directly on the bike (instead of carrying it in the back pack). I could not not find anything that fit my needs.

Then I designed this case.

It is design to fit perfectly the main tube of the ebike Cube nuride.
However, I linked the fusion360 source file if anyone wants to adapt for his own bike.

You attach it to the frame using the two holes of the bottle holder (64mm standard).
You'll probably need some training to succesfuly insert the whole chain in the case (first put the core at the bottom). But once you get the trick, it takes seconds to put it in there.

I tested this case on ride several times, and it secures perfectly the chain : no wiggling, jolting or any noise due to vibration of the road.


Feel free to remix it !
Enjoy
