BOX Two Prime 9 Chain - 126L brings simplicity and strength to modern drivetrains with the perfect balance of durability, precision, and wide-range performance. Designed for riders who want fewer gears but all the range, this chain delivers smooth shifting and lasting reliability across a wide variety of setups.
Built around
Prime 9 Technology, the BOX Two chain combines the ruggedness of traditional drivetrains with the crisp performance of narrow-wide chainring compatibility. Its unique design uses the outer width of a standard 9-speed chain but a narrower inner width to match 10-, 11-, and 12-speed narrow-wide chainrings. The result: quieter operation, better chain retention, and less maintenance on rough rides.
- Prime 9 Technology offers wide-range gearing with fewer cogs for simpler, more reliable performance.
- Wider chain construction boosts strength and longevity for aggressive trail use.
- Compatible with most 10-, 11-, and 12-speed narrow-wide chainrings plus BMX 3/32" chainrings and cogs.
- Engineered for smooth, consistent shifting and reduced drivetrain wear.
Whether it’s powering through mud, dust, or daily miles, the
BOX Two Prime 9 Chain keeps your drivetrain running strong with less fuss and more ride time.
