Product Origin

Our disc rotors are manufactured in Taiwan and China to European standards. Don't be concerned about the quality. We have many customers using our rotors and the WA Stuntors use them on their stunt bikes.

Many of the other discs are all from the same group of factories. Mostly, they all look the same but the quality varies a great deal. Many do not have any carbon content so the braking ability is poor, some have too much so they rust quickly, some use case steel carriers making them heavy while others have not been ground post production and therefore vary in thickness and create a heavy pulsing when braking.

We are very involved with our manufacturing process and quality assurance. We also offer full follow up support and provide a 24 month warranty to support our customers.
