Can you take a picture.The Durablue axle uses the clips the axle nuts jam aginst the clips and tight everything up.It should have 2 clips.One on brake side to hold the brake rotor hub on.Then the other one on the chain sprocket side.You install the push pull axle nut then side the clip into the grove and tighten the axle nut up .You hold the round side of the axle nut and tighten the axle bolt,and it expands and get tight on the clips and hols everthing together like the Hondas axles, I hope this help if you need any thing else with it let me know i have durablue myself,but im not using it anymore
