Lundeng OEM RD-TZ31 Rear Derailleur for Mountain Bike

Model: The latest version of the Shimano RD-TZ30 is the Shimano RD-TZ31. It is the same size and type as the RD-TZ30, and comes in a black color. This rear derailleur weighs around 300g per piece.

There are two types of the RD-TZ31: Direct Mount or Hanger Mount. How do you choose between Direct Mount and Hanger Mount? The Direct Mount attaches directly to the frame of the bike. If your bike has a dropout, you will need the Direct Mount type. On the other hand, if your bike has a "claw" type with a "C" shaped hook that goes around the solid axle, you will need the Hanger Mount.

The Shimano RD-TZ31 6/7 Speed Rear Derailleur is the Direct Mount type specifically designed for mountain bikes. It is made of high-quality plastic and alloy materials and is suitable for use with a 6/7 grade freewheel. This rear derailleur is equipped with SIS index shift and is compatible with both mountain bikes and road bikes. It is primarily intended for use with aluminum alloy bike frames.

Before purchasing the Shimano RD-TZ31 6/7 Speed Rear Derailleur, it is important to check the mount type of your original part. If your bike frame has a hook as shown in the picture, you can use this Direct Mount type. Make sure to choose the correct mount type to ensure proper compatibility with your bike.
