YBN MK120 12-Speed Flattop Road Chain

YBN's MK120 12-Speed Flattop Road Chain offers advanced engineering for narrow drivetrains. Its patented Ni-PTFE treatment and precise chamfering ensure whisper-quiet, smooth shifting under any load. Enhanced with DHA hardening and Ti-Nitride coating, the chain delivers exceptional durability, extending life up to 8,000 kilometers, or longer when waxed. Hollow pins reduce weight for race-ready performance, while circle riveting boosts strength without increasing width. The included patented QRS link provides easy connection and maintenance, making the MK120 a top choice for reliability and efficiency in high-performance road cycling.

Thin To Win

YBN's MK120 12-Speed Flattop Road Chain sets the standard for technological innovation in narrow drivetrains. Drawing on decades of chain manufacturing experience, YBN enters the 12sp arena with an ingenious design that excels in every performance category. Whisper quiet due to YBN's patented Ni-PTFE treatment and precise chamfering, the MK120 shifts seamlessly under any load, light or heavy. Add DHA hardening and YBN's Ti-Nitride treatment for extra durability and chain life is extended to YBN's highest at 8,000 kilometers (longer with wax). Hollow pins keep the chain light for all-out race performance while circle riveting increases strength without adding width.

Complete the package with YBN's patented QRS link (one included with chain). Unlike other manufacturers' master links, the QRS link can be re-used five times.

Compatible with SRAM 12sp Road and Gravel drivetrains, the MK120 is rugged enough to ride every day but be absolutely sure it's on your bike for race day.
