BB219KRO (Blue) made a sensational debut in 1988 as “RK Blue”.
BB219KRO has been the Champions’ choice in the highest categories such as KF class and OK class.
The latest technology is used in every component in these chains.

Q: Do the O-ring (sealed) chains create more friction than Non sealed (Non O-ring) chains?
A: No, absolutely not.
Friction is dramatically reduced once the chain heats up (proved by every Dyno test and by the results).
KRO’s stronger components and self-lubricant construction help race performance and a longer life. (3-4 times longer than Non sealed (Non O-ring) chains per our test data.)
