WELCOME TO SEIDO
SEIDO Components ([se\ːdo] from the Japanese 精度 meaning precision or accuracy) aims
to deliver high-quality components and accessories tailored to the needs of modern bicycles
and their riders. Without trying to re-invent the wheel we strive for constant development and
the refinement of established technologies. Our goal is to make parts that meet a specific
need in ways only ever as complex as necessary. Born of the desire to produce parts we
could not find anywhere else, Seido grew alongside the development of our range of com-
plete Bombtrack bikes. Now helping all riders benefit from the solutions we’ve created, Seido
makes these technologies universally available.
