RK’s 420MXU2 will come with RK’s U-Seal for increased durability without increasing drag. RK’s UW-Ring seals utilize triple barrier grease protection plus anti-debris technology. Anti-debris protection is vitally important to maximize chain wear life by eliminating debris friction between internal components. RK’s U & UW seals also feature small contact points to reduce cold start drag. U & UW ring thickness is 50% thinner than O-ring with longer life time. MXU2 is available in 420 pitch.
