The SRAM X.3 7-Speed Rear Trigger Shifter is a budget-friendly, entry-level mechanical shifter designed specifically for the right-hand side of flat handlebars. Unlike previous MRX models, it transitions from a twist grip to a more traditional 2-lever thumb trigger layout, offering a completely new derailleur standard.

Key Technical Specifications:

• Placement: Right-hand side (rear derailleur control).
• Speed Capacity: 7-Speed.
• Shifter Type: Trigger (Dual-lever push design).
• Actuation Ratio: SRAM 1:1 Actuation Ratio.
• Derailleur Compatibility: Only compatible with SRAM 1:1 rear derailleurs (e.g., SRAM X3, X4, or X5 7/8-speed models). Not compatible with Shimano rear derailleurs.
• Model ID / Part Number: SL-X3-A1 / 00.7015.093.040.

Core Features:

• 1:1 Actuation Technology:
  Pulls an equal amount of cable for every unit of derailleur movement, making the system highly tolerant to contamination like mud, grit, or water. This ensures easy tuning and maintenance.
• 2-Lever Ergonomics:
  Features two distinct thumb levers for managing shifts up and down the cassette. This design mimics the mechanical motion found on high-end SRAM mountain bike drivetrains.
• Gear Indicator:
  Includes an integrated composite mechanical window display, conveniently positioned in front of the handlebar clamp for quick and easy visual gear checks.
• StraightShot Cable Design:
  Designed with an accessible housing structure that allows for quick and straightforward replacement or installation of a new inner shifter cable, without requiring disassembly of the entire shifter body.

This shifter is an excellent choice for riders seeking an affordable and reliable solution for their 7-speed drivetrain, with features that ensure durability, easy maintenance, and precise shifting performance.
