The SRAM MRX Comp 5-Speed Rear GripShift Shifter is a highly reliable, budget-friendly twist-style gear shifter designed for entry-level mountain bikes, hybrid commuter bikes, and children's bicycles.

Key Specifications & Features

• Drivetrain Layout:
  Engineered explicitly as an indexed 5-speed rear shifter, built for 1x5 or 3x5 gearing configurations.
• Shimano Derailleur Compatibility:
  Operates on a standard 2:1 cable pull ratio. Unlike traditional SRAM shifters that require proprietary SRAM derailleurs, the MRX Comp series is explicitly engineered to be compatible with Shimano MTB rear derailleurs and standard 5-speed cassettes.
• SRS Technology:
  Built with SRAM’s Sequential Revolution Shifting (SRS) system. This mechanical internal assist ensures lightweight, precise, and crisp indexed shifting every time you twist.
• Body & Grip Layout:
  Features a lightweight Grilon composite 50mm "Shorty" body paired with an extra-soft, overmolded dual-density rubber grip texture.
• Visual Indicator:
  Equipped with an integrated "Quick View" display lens that makes it easy for the rider to verify exactly which gear is currently selected.
• Cable Management:
  Ships with a pre-installed slick-coated steel inner derailleur cable. Maintenance is simplified via a sealed external port, allowing you to completely change your shift cables down the road without physically removing the entire shifter assembly from your handlebar.

This shifter combines ease of use, durability, and compatibility, making it a fantastic choice for a variety of riders and bike setups.
