Those in the know roll with ESI Chunky Silicone grips. They are simple, light, and ultra-comfortable. Something that's been lost with the widespread adoption of lock-on grips is the ability to use the entire grip surface. Grips with double lock-rings are not only heavy, but uncomfortable for some riders. Especially when the outside of your hand rests on the hard lock collar. Since ESI grips are made out of 100% silicone foam, you can move your hand around a bit and stay comfortable no matter what. Plus, even though they are soft and cushy, they last a long time. One of our favorite features of the ESI Silicone Grips is that the grip conforms to the shape of your hand. This results in a custom feel and extreme responsiveness.
