This option can be used to tune the rear chassis flex of your R1B. With two options, Medium-Soft and Medium, these plates slot just under the kit-standard aluminum brace in terms of flexibility.

However, they provide a different feel compared to the aluminum brace, as these braces have more spring due to their material and isotropic layup construction, which delivers exceptional and consistent flex characteristics.

Key Features and Specifications:

• R1 Wurks genuine option part
• Rigid Isotropic Layup 

Includes: 

• x1 Rear chassis brace of selected stiffness
• x4 Threaded inserts 
  

Weight Comparison:

Assembly Note:

• CA glue can be applied to the inserts or the carbon insert holes if desired. Be sure not to get any glue on the threads.
