It seems as though we have a solution! I would like to extend a massive "thank you!" to @
Hawk77FT for his help in tracking down this fix and putting together a DIY with pictures.
IRP has indeed released a fix for the rattle that occurs in the V3 short shifter. It consists of a rubber gasket, four plastic washers, and an aluminum spacer:
In addition to this, he fabricated a custom mount, made of carbon fiber a foam/rubber material:
Now, onto the DIY for the fix: (again, huge thanks to @
Hawk77FT)
1.) Make sure that the vertical handle position has about 2mm clearance:
2. This image shows the gaskets fitment:
3. If the shaft in this picture moves side to side, put on some thread locker.
4. The black aluminum cylinder needs to be pushed in this position:
5. Undo the screw pointed out in Image 1 and pull it a little so the cable has a small amount of tension. You will see the top cylinder (Image 2) moving a little).
Enjoy!
