1: High Tech Design and Manufacturing Process |
- Our
unique 5-spoke carbon composite wheel is made using the latest technology,
materials and manufacturing processes. This lightweight and exceedingly
strong wheel is suitable for both racing and street racing use. The
wheels have been tested at Rim Technology, Eurotype
Test Centre and German TUV, and passed all the tests for road certification.
And most important of all, our wheels are unique in that they are created
as a single unit - we don’t bond pieces together.
- BST
wheels are unique - monocoque (single unit) design
with 5 hollow spokes and are suitable for both street and race use.
- BST
wheels will save you anything between 40% - 60% in
weight, and more importantly, are designed to deliver the lowest Moment
of Inertia - the critical factor that affects the performance of the
bike.
- Because
we can engineer with carbon fibre and maximise on its properties of
high strength and low weight, we have reduced the weight in the spokes
and rim without compromising strength. The weight is therefore concentrated
in the hub, which means that rotational inertia is reduced,
making the bike easier to handle, and allowing you to accelerate quicker
and brake later. So not only is the wheel lighter, but it is engineered
for maximum performance.
- The
entire process is managed under ISO9001:2000 standards.
We design the tooling, moulds, wheel and the hubs and manufacture them
onsite. Cutting machines such as those used in the aeronautical industry
ensure that the process is guaranteed and repeatable to our high standards.
Layup is done in a clean room (dust-free).
- The
wheels are cured in an Autoclave at 125 degrees C and
6 bar of pressure. This ensures the best compaction and surface finish.
- Every
step of the process is logged and the entire history
of each wheel is stored with its unique Serial Number.
- The
carbon fibre we use is a woven and unidirectional format,
and is embedded in a resin matrix made from toughened epoxy. Pre-preg
is used as the machine application of the specific resin systems ensures
the most controlled and even application and therefore the highest quality
material for use in all BST products.
- The
hub is attached to the carbon wheel using a unique
fastening system combining high strength aerospace fasteners with mechanical
locking mechanisms as well as high strength aerospace adhesive.
