Shimano Tourney TX800 7/8-Speed Rear Derailleur (100% ORIGINAL)

Upgrade or refresh your entry-level mountain, hybrid, or touring bike with the genuine Shimano Tourney RD-TX800 rear derailleur. Designed to deliver smooth, reliable, and stress-free gear changes, this derailleur fully supports Shimano's SIS Index Shifting technology. Featuring a durable double servo-panta mechanism, it ensures the pulley tracking stays incredibly close to the cassette cogs for fast, light-action shifting across 7-speed or 8-speed drivetrains.

FEATURES & BENEFITS

• Double Servo-Panta Mechanism: Maximizes shifting accuracy by tracking the cassette contours flawlessly. This keeps gear changes crisp and consistent while reducing drivetrain noise.
• Light Action Performance: Optimizes spring tension to provide smooth, low-effort shifting at the handlebar lever—perfect for long, casual, or stress-free daily commutes.
• Oversized 13T Pulleys: Equipped with dual 13-tooth guide and tension pulleys. The larger pulley design reduces chain friction, minimizes chain wrap wear, and handles chain slack smoothly.
• User-Friendly Installation: Built with an Allen key type inner cable fixing bolt for quick, secure cable clamping and easier routine tuning adjustments.
