I read so many posts about the tri-ax shifter being noisy that I decided to use all of the stock insulation with the tri-ax shifter and also insulated the shifter to handle with rubber. The rubber I used is cut out from a piece of rubber from a jar opener which I bought for less than $1.00 from Wal-Mart. I doubled it up to make it about 1/16 thick and used it on both sides of the handle. The shifter is very precise and is now, to my ears, as quiet as stock.
