aqxreight Rear Derailleur for Mountain Bikes Achieving 6, 7, 8 Speed Control Bike Rear Derailleur TY300,TX35 Upgrade
Main highlights- This is a rear derailleur for mountain bikes, often simply called a rear derailleur. It's one of the most crucial and precise components of a 's drivetrain, responsible for guiding the chain between different sprockets through precise lateral movement during gear shifts.
- Receiving and Transmitting Shifting Commands: The rear derailleur is a precision mechanical actuator. It connects to the shifters via a shift cable, translating the rider's hand movements—tightening or releasing the cable—into precise lateral movement. As an upgrade to improve performance, compared to the TX35, optimized pulley bearings or internal structures can result in smoother chain movement and lighter shifting.
- Model Positioning: TY300 is the specific model number, while TX35 Upgrade clearly indicates it's an improved version of the previous TX35 model. This means the rear derailleur has been optimized in terms of materials, structural design, or performance, and is compatible with 6-speed, 7-speed, and 8-speed drivetrains.
- Maintaining Chain Tension Force: A powerful spring inside the rear derailleur constantly tries to pull the derailleur arm forward. This design allows the derailleur to automatically maintain proper chain tension regardless of whether the chain is on the largest or smallest sprocket, preventing slack, vibration, or slippage.
- Gear Shifting: When the rider operates the shifters or turnshifts, the rear derailleur moves precisely laterally under tension. Two guide pulleys on the derailleur guide the chain from its current sprocket to the target sprocket. This directly changes the gear ratio, making climbing easier or riding faster on flat ground.
