Im going to figure out a better way to attach them, otherwise they will pop off and Ill lose them. No more floor mats. I had a quality Fellows brand wrist rest purchased and in daily use for the past 15 years. These are exactly what I needed! Have to jiggle the key in and out of the lock cylinder, but it does function. Feel just like those $2 ones you buy at the drug store. So, I popped these babies on and took them on a test run. 1kg but the hanger will support bikes up to 18kg. As soon as they arrived I realised this was a mistake. If I still lived in IL, heck no.
