Description

JT Twinstar - Steel/aluminum hybrid sprocket .

 

The JT Twinstar sprockets are made from a combination of durable steel and lightweight aluminum.

 

The inner circle made of the special aluminum alloy has about 11 times the strength of pure aluminum and thus almost reaches the strength of steel.

The chain itself runs on the steel sprocket. This results in the perfect combination of weight saving and longer service life.

 

Experience shows that JT Twinstar sprockets last approximately three times longer than pure aluminum sprockets and are 50% lighter than steel sprockets.

JT Twinstar sprockets are among the highest quality and most technically advanced sprockets in the world.
