OK I got the Lizard Skins from Nashbar and they were nearly impossible to get on the bar ends!!! I didn't have hairspray like the package suggests to use, so I had to go buy a can. It didn't work, so I used a tiny bit of vaseline and that got them slippery enough to get on somewhat.
Anyway, I noticed that they really don't work that well. I got them for the padding they would add, unfortunatly they are not very thick. I usually grip the ends of the bar ends, putting the part of each palm (closest to the thumb) on the end of each bar.
The problem, I need padding for the very ends of the bars. Kinda of like a cushion for the bottom of the leg of a chair. I considered taking 2 stress balls and cutting a little hole in each one and popping those onto the ends but I am thinking that will look really stupid and they will slip off easily.
