This may be a stupid question. I took the grips off of my bike and these grips had a closed end on them. I installed the new grips that had an open end on the bike and the end caps that they supplied didn't seem to fit. I measured my handlebars and they measured 5/8", so I went to the bike shop thinking that I had a smaller diameter handlebar. They sold me (after measuring) 5/8" end plugs for the handlebar. I got home and tried to install these, and they also don't seem to fit. I tried hammering the damn things in, and they still won't go in.
So, my dumb questions are:
1.) How do you install these things??
2.) Do you even use them, and if not, what do you do? Leave an open end on your handlebar exposed?
3.) What is a good grip that is fairly thick with closed ends?
