Lundeng OEM RD-TZ31 Rear Derailleur for Mountain Bike

Shimano RD-TZ31, the latest version of the RD-TZ30, is available in black with a weight of about 300g per piece. This model comes in two types: Direct Mount or Hanger Mount (Hub Bolt Mount). The Direct Mount type bolts directly to the frame, making it suitable for bikes with dropouts. On the other hand, the Hanger Mount type features a "claw" with a "C-shaped hook that goes around the solid axle, making it ideal for bikes with this setup.

The Shimano RD-TZ31 6/7 Speed Rear Derailleur is a Direct Mount type, not a hub bolt mount type. It is made of high-quality plastic and alloy, designed for use with 6/7 grade freewheels and SIS index shift systems, making it suitable for both mountain and road bikes. This derailleur is primarily used in aluminum alloy bike frames.

Before purchasing, please ensure to check the mount type of your original part. If your bike frame has a hook as shown in the picture, then this Direct Mount derailleur is compatible. Remember, the type of mount you choose will depend on the specific setup of your bike's frame.
