SLA and DHA explained

YBN spent two years developing its SLA (Superior Lubricating Aid) Ni-PTFE coating. It cuts friction, runs quietly, resists sticking dirt and is easy to clean, and YBN says it lifts durability by 200%. DHA chromium carbide surface hardening increases the hardness of the pins so they keep performing even with abrasive grit around, and adds rust resistance.

Compatibility & fit

YBN lists the MK120 for SRAM Red XPLR 13, Red AXS, Force AXS and Rival AXS, and also lists Shimano Dura-Ace R9200 and Campagnolo Super Record and Chorus 12 speed. YBN rates it for road and gravel use; it is not listed as e-bike rated. It joins with YBN's MK12 connector.

Our workshop can size and fit your chain and check your cassette and chainrings for wear.
