The Bones RS Levers for my rack had worked fantastic for years. Unfortunately one snapped when I was tightening (fitting for the season and seasons use). Due to COVID-19 it took a bit of time to get the replacement. I was very excited to install. Unfortunately as I was tightening the replacement lever snapped. The inner screw is difficult to tighten without the lever...I highly recommend this bike rack perhaps mine is just too old to repair.
