We have been building carbon fiber bike frames since 1988. Our durable
frames have performed well in world class competitions like the Hawaii
Ironman and the Tour de France. Some very famous athletes have raced
on our bikes, often under different brands.
We are pleased to see
that most of the other quality frame builders have finally realized
that carbon fiber is the material of choice for a bicycle frame.
Our long experience with the material gives us the advantage in knowing
how to get the best ride quality and longevity by orienting the fiber
in the most effective manner.
Also see our award-winning bamboo frames
which, like our carbon fiber frames, are available in myriad geometries
and sizes, each one a unique and built-to-order work of art.
While
we enjoy making custom frames (from 30 cm to 70 cm frame sizes),
only about 12% of the population really needs a full custom frame.
For the rest of us, you can get many custom options without paying
for full custom. Buy a BarStem with the savings!
Technical superiority
and customer service is our specialty. I invite you to find out why
our products are so exceptional and to join our growing family of
satisfied cyclists.
Our classic frame, backed by a 25 year warranty. The 54 cm size weighs 2.5 pounds.
The Tetra was originally designed
in 1987 and has been refined to its current incarnation
over the years. As the oldest continuously produced
model of carbon fiber bicycle frame in the world, it
has evolved to a state of perfection and value unmatched
by any other frame.
Consider these points:
A frame with over 120,000 miles "feels as lively as
it did when it was new" according to the owner of
that bike.
A three time winner of the Tour
de France declared "It's
the best bike I have ever ridden"
The Tetra is molded
in one layup, where the tubes are mitered to each other
and laminated directly to each other with metal dies.
The resulting joint has a long tapered transition from
one tube to the next, following the stresses evenly.
The
Tetra tubes were designed to have the optimum stiffness
to weight ratio and also have a thick enough wall to
be crash tolerant. The fiber orientation of the tubes
gives the best combination of stiffness and comfort
for everyday riding. The intermediate modulus fiber
is strong and very stiff but not too brittle.

This is not just
a cool bike. It is appropriate for everyday use and
for racing. The vibration damping is a performance
advantage on longer rides. Each frame is built to order
and every frame is a unique. Tubes are selected for
the weight of the rider. The geometry of the frame
can be any of our usual geometries: Pro, Tri or Cross.
Custom frames can also be made.
