Why choose us?

Home Grown

Since SpD Factory
Developments began, the Company ethos has remained unchanged – ‘Superb quality and nothing less’. Every item that we manufacture or product that we market from other manufacturers must answer one simple question – “Would we be proud to put that on our own bike?”. If the answer is no then we don’t sell it.



In a word, superb! With attention to detail even on a plain old bolt! Very happy with results and well worth the wait.
