Box Two 9-Speed X-Wide Derailleur

The Box Two Prime 9 Rear Derailleur is very similar to the Box One version however, to be more wallet-friendly, it offers a non-adjustable Tri-Pack™ Clutch, bushing pulleys and some muted finishes. Box Two rear derailleurs are still optimized for 11-50t cassettes and offer durability and performance for the most demanding terrain, just at a lower price!
