The SRAM GXDH 7-Speed Medium Cage A3 Rear Derailleur is built for downhill precision, durability, and control. Designed with proven World Championship technology, it delivers crisp, consistent shifting while reducing chain noise and unwanted movement. With a focus on strength, accuracy, and affordability, it provides a reliable drivetrain solution that lets you concentrate on performance.

Key Features and Benefits:

• X-HORIZON™ derailleur design: Limits horizontal movement of the cage, which reduces ghost shifting and unwanted chain movement. The outcome is a more stable and consistent drivetrain that stays precise even under the toughest downhill conditions.
• X-ACTUATION™ technology: Maintains accurate shifting across the 7-speed range by controlling cable pull with exact ratios. This ensures dependable gear changes every time, giving riders confidence when every shift counts.
• 12-tooth X-SYNC™ pulley wheels: Engineered with narrow-wide tooth profiles to improve chain retention and engagement. This results in smoother running and reduced risk of dropped chains, keeping momentum steady.
• Noise reduction focus: The derailleur design minimizes chain slap by controlling cage movement and absorbing excess vibration. The outcome is a quieter, more focused ride with fewer distractions.
• Full DH drivetrain compatibility: Works seamlessly with SRAM’s X01 DH system, offering cross-compatibility at a more accessible price point. This provides a dependable and cost-effective option for dedicated downhill setups.

Consistency in gear changes is essential in downhill riding where fractions of a second can matter. The precise engineering of the X-HORIZON™ design and X-ACTUATION™ technology ensures gears engage quickly and accurately, reducing the chance of missed shifts. Combined with improved chain retention and noise control, the derailleur gives riders a drivetrain that performs reliably on demanding terrain.

Built for riders who want proven downhill technology without excess cost, the GXDH 7-Speed Rear Derailleur offers accuracy, durability, and control in one package. Make it the dependable upgrade that keeps your drivetrain sharp run after run.
