Three Prime 9 Chain - 126L

The BOX Three Prime 9 Chain delivers smooth, dependable shifting for riders who demand simplicity and performance in equal measure. Designed around BOX’s Prime 9 Technology, this chain offers a wide gear range without the clutter of extra cogs, keeping your drivetrain light, quiet, and easy to maintain.

Built for strength and durability, the Prime 9 Chain uses a wider profile that resists wear and holds up under hard pedaling, whether tackling steep climbs or hammering through the bike park. Its unique inner width design makes it compatible with most 10-, 11-, and 12-speed narrow-wide chainrings, giving riders flexibility across different setups—from trail bikes to BMX builds.

• Prime 9 Technology provides a simple, wide-range drivetrain with fewer parts to maintain
• Wider chain plates enhance strength and longevity for aggressive riding
• Narrow inner width fits most modern narrow-wide chainrings (10/11/12-speed and BMX 3/32")
• Optimized for crisp, reliable 9-speed performance

Perfect for riders who prefer a no-nonsense setup that just works, the BOX Three Prime 9 Chain keeps things smooth, strong, and ready for every ride.
