Now that I have your attention has anyone used them. Basically a thick foam tube that slides over the handgrips on your bike. I hear they are good for long rides. Am doing ride from Melbourne to Canberra and thought they may help with fatigue and vibration. Have seen them on eBay. Just after opinions. I have a metal plate in my right hand and vibration tends to cramp it up on long rides.
Bloody work well on my Super Tenere, take all the tingles out of the bars, and makes for a thicker grip for my big mitts.
As a side note wazza, Be careful when sliding the Clarke Rubber stuff onto the grips, it tears fairly easy if you force it too much. Might be just as well it comes in a metre !!
