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.
