ESI Chunky Silicone grips are a premium product offered as an upgrade from double lock-on grips. They are about 60g lighter than a lock-on and offer more comfort because the material is softer and they don’t have the collar at either end – they are fine to use without gloves.
Dimensionally they are the same as the Superstar Supagripa they replaced – you could trim these for smaller hands very easily and they offer a racing version for a thinner grip.
Installation was very simple: First put in the included end plugs, then spray something that will dry (I used window cleaner) onto the bars and inside the grips and twist on. After a few minutes they stay in place very well and do not slip.
The end plugs are quite rubbery so the bike does not fall when it is leant against things, they also add a few millimetres to your bar length.
Durability is a potential issue – mine have taken a cut from the metal edge of my storage locker and the split is slowly creeping. I expect they may need to be replaced after about 6 months which leads on to…
Cost – they don’t seem to have been copied and are not discounted, leaving them at £16. Although the packaging claims they are thicker under the palm mine look *exactly* like they have been cut from a length of pipe lagging. You don’t get much for your money but is it a case of less is more?
