R1WURKS (B7 Series) Ultra-Lightweight HD CVA Bones, 69mm, Black

Ultra-lightweight bones take the lightweight design to the next level. With an even smaller shaft diameter, rotational inertia is further minimized, allowing for the faster acceleration and deceleration that stock racers crave.

Application: These ultra-lightweight bones are optimized for stock racing, specifically for the 21.5 to 17.5 classes. For lower wind classes, such as 13.5 and Modified, it is recommended to use the #900067 R1WURKS B7 Lightweight HD CVA Bones, 69mm.

Key Features and Specifications:

  • Weighing in at just 7.2g for the pair, these outdrives are 34.9% lighter than the standard bones.
  • Made from treated high-yield strength steel with exceptional elasticity and toughness
  • Durable gloss black oxide coating
  • Improved acceleration
  • Better braking response 
  • Increased power transfer 
  • Lower motor temperatures 
  • Laser-etched logos and identification markings

Includes:

  • Two CVA bones

Replaces: AE RC10B7 HD CVA Bones, 69mm# 92454

Fits:

  • B7
  • B7D

Best performance when used with: #900071 Lightweight B7 Rear CVA Axle

Team Driver Tip: Use R1WURKS Black WS2 Grease at the joint and drive cup during assembly.
