Super Shims

Eliminate the play from your derailleur mounting bolt and immediately improve your shifting! This product is a great bang for your buck!

The kit uses the existing SRAM bolt, and adds a shim and wave spring. The wave spring adds compression force to the assembly which removes the wiggle, while still allowing the derailleur to pivot about the bolt when needed. The o-rings are included to replace the SRAM ones in case they are damaged.

The kit includes:

• Small o-ring, QTY 2: 1mm thickness, 8.5mm ID, 10.5mm OD..
  
• Large o-ring, QTY 1: 1.5mm thickness, 13mm ID, 16mm OD.. 
  
• Stainless steel shim, QTY 1: 0.3mm thickness, 10mm ID, 16mm OD. 
  
• Stainless steel wave spring, QTY 1: 0.3mm thickness, ~10.5mm ID, ~15mm OD.

Fits SRAM Eagle mechanical (X01 and XX1) and SRAM AXS Eagle (GX, X01, and XX1). They do not fit GX 12 speed, or any 11 speed derailleurs.
