Choose your chain

From a plain chain for everyday riding to a sealed X-ring for the hardest use. Sealed chains keep their grease inside the links, so they last longer and need less care.

01 · Everyday commuting

Normal Black Chain

A plain black chain for standard replacement on small commuter bikes. Clean and lube it often and it keeps running smoothly.

Seal: None
Plates: Standard

02 · Work bikes and loads

Heavy Duty Chain

Thicker plates for strength where it counts: delivery bikes, carrying loads and riding two-up. A plain chain that rewards regular lube.

Seal: None
Plates: Heavy duty

03 · Daily riding, longer life

O-Ring Heavy Duty Chain

Rubber O-rings seal the grease inside every link, so the chain stays lubricated, stretches less and lasts far longer than a plain chain.

Seal: O-ring
Plates: Heavy duty

04 · Hard riding and racing

X-Ring Heavy Duty Chain

X-shaped seals touch the plates at four points instead of two: the sealed-in grease of an O-ring with less drag, for hard acceleration and long rides.

Seal: X-ring
Plates: Heavy duty

42T 428 pitch, 12.7 mm HRC 40–45

Every sprocket starts as a steel blank in our factory

We cut, harden and check our sprockets ourselves, so we know exactly what goes into each one. If your bike needs a tooth count we don't stock, we can make it.
