Worked perfectly for trueing my 15mm and 20mm through axle wheels on a single sided trueing stand. If not then Ill have to remove the entire setup to correct it. 5 Sketchers, so I got these in a 9-10. Otherwise very comfortable And I relax and dye it. I used up one and had to order another. I dont notice any difference in the noise cancellation, and they appear to function the same. I would recommend keeping a pack of wet wipes in the car or wherever you keep the Kupper mounts to wash off the car wherever youre going to mount them. well, mine appear to be faulty. Screw (7mm) in the plug adapter should be only hand tight.
