KMC’s Newest X12 Chain: Thinner, Faster, Stronger
Fulfilling KMC’s premium X series status, enhanced inner X-bridge plate design guides gear teeth into the chain smoothly. In addition, optimal dynamic chamfering augments chain performance while avoiding shifting interference. The newest X12 chain possesses upgraded pin power (+400 kgf) for improved robustness and durability for increasing chain life and neutralizing the stresses caused by severe chain lines inherent to 12 speed systems. The Titanium Carbon Nitride Coating achieves high surface hardness and debris repulsion.
KMC always focuses on innovation and has led the chain industry for over 40 years. KMC has received multiple design awards including the recently awarded 2017 iF Design Award in Asia when X12 was first released.
New X12 chain accurately avoids gear interference, shifts smoothly, and is perfectly compatible with all 12 speed drivetrain systems and components. KMC has created a new benchmark for 12 speed chains.
