kryptonite GRAVITY WHEELNUTZ

[MSantos]

Hello
I hope you are well and safe.

I'm trying to buy a Kryptonite Wheelnutz. They have 3 sizes: m10, M9, and M3/8.

how do I know the right size?

I want to install this on KTM: https://www.ktm-bikes.at/nc/en/bikedetail/singlebike/macina-gran-510.html

thanks for your help and assistance.

Best

I have a similar device from Abus. Mine depends on size of skewer. (sp ?) Mine was m9. Maybe e mail manufacturer of seller to be sure.

are they through axle or just standard quick release? myselfI don't want to lay. e bike down just too heavy to manage that way.

They have a nut. Cannot take nut off, because it has a cover, if bike is right side up. It is an antitheft device that prevents someone from stealing your wheel or taking your wheel off that would otherwise be attached with quick release. If you lock your bike properly they should not be able to put bike sideways or upside down.

but it makes it a real hassle to remove a wheel for yourself. or if the bike needs repaired and you take it into a shop.

Thanks Guys... I got info from KTM. they use quick release.
Big advantage is left bike in public and people of mind that tyre will be there when back.

Measure the thread diameter with the flat part of a caliper outside the bolt. Measure the threads per inch or millimeters per thread with a thread gauge. Standard ANSI 3/8 thread is 18 or 24 tpi, bike axles are 26 tpi for historical reasons. Metric system has no standards agency setting mm per thread, Jap & German are usually different. Bike hub motor manufacturers have picked a thread that doesn't match anything else.
