Q: Can I use these with bar end mirrors? That is to say, can the end cap be removed and the end left open?
A: Our metric grips do not have an open end. There is a piece of rubber at the end of the grips with a small hole for a Phillips Head screw to go through to hold the end caps on. We do have customers who cut off the rubber piece but then you would have to glue the end cap onto your handlebar.
