Giant TCR ISP spacer top cap MY21+

Amazing rubber ISP spacer

I had creaking in the ISP mask that was driving me nuts. I torqued and re-torqued the mask bolt, modified the tape between the carbon ISP and the metal mask, greased every screw and metal contact surface and used carbon friction paste between the rails and the carbon clamp in the off chance that creaking was from the mask, cradle, and saddle rails. Nothing worked and I was planning to get a new bike because I hate creaky bikes, but I found this little piece of rubber spacer and it did the trick! I’m planning to buy more as spares in case they ever stop selling these!
