Description
JT Rear Sprockets – Alloy
Made from the highest-grade aluminium available – 7075-T6. Sourced from Austria, the 7075-T6 alloy comes off the same production line as the aluminium used in the Airbus planes.
The heart of JT Sprockets and their durability, is the material used and the accuracy of the machining process. Every JT sprocket is made the right way, by hobbing, machining and drilling. This is the only way to achieve the closest tolerances and the best tooth profiles. And every sprocket goes through 10 individual quality control checks before it leaves the factory. That is why JT Sprockets can guarantee the quality of every JT Sprocket sold.
JT Sprockets – the World’s No.1 manufacturer of aftermarket sprockets.
