RK Excel GB428MXU DRIVE CHAIN GOLD 428 X 130 GB428MXU-130

RK’s MXU features ultra-thin UW-seals which is perfect for bikes with narrow clearance and delivers triple the life expectancy when compared to a non-sealed chain. 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 UW seals also feature small contact points to reduce cold start drag. UW ring thickness is 50% thinner than O-ring with longer life time. MXU is currently available in 520 pitch
