Brand new, genuine Shimano RD-TX800 Rear Derailleur. This was purchased as a replacement for my son's Cannondale mountain bike but was never installed or used. It remains in its original manufacturer packaging with the instructions included.

Technical Specifications:

  • Series: Tourney TX

  • Compatibility: 7-speed or 8-speed drivetrains

  • Mount Type: Direct Attachment (standard)

  • Color: Black

  • Design: Double Cardinal design for precise and reliable shifting.

This is a perfect, cost-effective replacement for mountain bikes or hybrid bikes. Avoid the "knock-off" versions found online—this is a genuine Shimano part.
