Chain 520 ProX X-Ring – 120 links, X-ring (enduro and road)

Chain with X-rings. The seal keeps the lubricant inside the pin and keeps water and sand out, so it lasts several times longer than an unsealed chain. The X profile has less contact area than an older O-ring, meaning less friction for the same sealing. Size 520, 120 links, ProX X-Ring series. Supplied with a connecting link. From the workshop: always replace the chain and both sprockets together. A new chain on worn sprockets destroys itself in a fraction of its life. SKU: 07.RC520120XC.
