Mitsubishi - Diamana RB -Series

The Mitsubishi - Diamana RB -Series is a premium aftermarket driver shaft from Mitsubishi Chemical's Diamana family, built on the RB-Series platform to deliver a mid-to-high launch profile with a smooth, active feel through the hitting zone and the consistent performance characteristics that serious players depend on for reliable carry distances and accessible ball flight from their driver. Constructed from high-modulus carbon fiber using Mitsubishi Chemical's precision manufacturing standards and the RB-Series-specific material layering that positions this shaft in the higher-launching, more active range of the Diamana driver family, it produces a mid-to-high launch trajectory with a smooth, responsive feel that complements players with moderate swing speeds and smoother tempo profiles who want a driver shaft that rewards fluid, well-timed swing mechanics with the carry height and stronger ball flight needed to maximize distance off the tee. The RB-Series designation within the Diamana driver lineup identifies a profile suited to players whose swing speed and tempo characteristics call for more launch assistance than the mid-launch options in the family provide — delivering a more accessible, carry-focused performance outcome through the same Diamana engineering quality and manufacturing precision that defines the family across all of its trajectory profiles.

Key Features:

• High-modulus carbon fiber construction with RB-Series-specific material layering delivers a smooth, active feel profile through impact with a mid-to-high launch trajectory suited to players with moderate swing speeds and smoother tempo profiles
• Mid-to-high launch profile produces an accessible, carry-oriented ball flight that helps players maximize driver distance through better launch conditions rather than requiring additional swing speed to achieve adequate carry
• Smooth, responsive feel through the hitting zone rewards fluid, well-timed swing mechanics with consistent carry distances and reliable ball flight across a range of swing conditions and course demands
• Mitsubishi Chemical manufacturing precision and Diamana platform validation ensure the RB-Series construction is executed with the material quality and engineering standards the brand is known for across its full aftermarket driver shaft lineup

Who Should Use It?

The Mitsubishi - Diamana RB -Series is the right shaft for mid-handicap players with swing speeds in the 82–102 mph range and smoother tempo profiles who want a premium aftermarket driver shaft delivering mid-to-high launch, more carry distance, and a smooth active feel through Mitsubishi Chemical's proven Diamana construction. If your driver consistently launches too low, leaves carry distance on the table, or feels unresponsive for your swing tempo and timing, this shaft provides a well-engineered and practically proven solution in the most accessible and carry-focused profile within the Diamana driver family.
