ESI Chunky grips are made from 100% silicone. They are easy to install and hold very well without twisting even in wet conditions. Shock-absorbing silicone conforms to the hands and offers excellent comfort. ESI grips can reduce problems like numbness and hand pain. They are used by top professional teams and racers.
I like these grips; they are attractive on my fixie, shock absorbing and don't twist. But they took a lot of brute force to install. Even the end caps were difficult to install. Notwithstanding multiple whacks with a mallet, the end caps still aren't seated right on my handlebars. These grips will probably last a long time, but when they finally give up the ghost, I'll be returning to Kraton rubber grips.
These are rather easy to install with the proper technique - ed
Pros: Attractive, shock absorbing and secure
Cons: Difficult to install
