2 Pieces Bike Nuts Rear Hub Axle Stainless Steel Nuts Flange Mountain fit for BMX Fixie M10 Axle Screw

I got these cause, hey they look cool, but when you put them on after tightening to my hub's spec they literally pop off. Didn't even try to ride with them on, and just put my old worn out ones back on. I have almost 10 years of bike repair experience, so I don't think this is user error.

Great product. Fit perfectly.

They look great and I can get them very tight... one of my favorite add on's to my bike I've made! Very happy.

Good quality.
