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

Why STT sprockets

Every sprocket starts as a steel blank in our own factory. Point at a feature to see what goes into it. Need a tooth count we don't stock? We can make it.

01 · Heat

Induction-hardened teeth

Every tooth is induction-hardened, so the teeth resist wear while the core stays tough enough to take hard gear changes.

02 · Fit

CNC-cut tooth profile

Teeth are CNC-cut to the 415, 420, 428, 520, 525 and 530 chain standards, so the chain seats exactly, runs quietly and wears evenly across every link.

03 · Finish

Black and gold series

Black and gold finishes protect the steel from rust and give the back of your bike a clean, sharp look.

04 · Quality

Checked every batch

Made in our own factory under an ISO 9001 quality system, with every batch checked before it is packed.

Technical data

Hardened to last
