origin of our project to develop Anchor was a single bike. We asked,
"Can we evolve our frame build further, departing from conventional
craftsmanship? Does it suffice to rely on the intuition of craftsmen
alone?" This one bike carried all the hopes of our technical
staff; intent on developing a world-class bike.
The best professional cycle racers not only train every day to improve
their skills, but request manufacturers to enhance their bike's
performance to the maximum extent possible. So they complained,
"This one is good at first, but tires my legs in the second
half," and "Don't you have any frame that spares my legs
for the final sprint?" The only way for our engineers to understand
and meet such requests was to translate them into numerical data.
The bike was meant as a go-between linking athletes with engineers.
We used our optimal structural analysis technology to analyze the
stress on the frame based on data from athletes' actual runs; scientifically
examine the strength necessary for each frame portion; and thus
determine the rigidity balance. In developing the ultimate frame,
we were helped by the expertise we gained from the development of
Neo-Cot, Bridgestone's original tubing technology.
Further, we used our motion analysis technology to simulate suspension
operation via the most advanced computer available, and thus discover
the optimum link structure and pivot position. We also relied on
our aerodynamics expertise, to conduct a wind tunnel test and thereby
determine the frame shape that minimizes air resistance against
a bicycle. Anchor refers both to evolution and a tribute to our
scientific analysis that explores unknown realms.
physiques vary considerably from each other. Also, pedaling
characteristics and positions vary from person to person.
For instance, Japanese and Westerners are quite different
in these regards. Anchor provides the best solution through
the optimum combination of various elements, including frame
material, shape and skeleton. We develop bikes ideal for Japanese,
through repeated testing and scientific analysis with the
participation of top athletes.

Though costly, these models will surely lead you to victory.
The high modulus carbon fiber
has a higher rigidity than normal carbon fiber. This fiber
can therefore be used to make a fabric that is lighter than
a normal carbon fiber fabric, but with rigidity equivalent
to the latter. If the same number of layers is used, the high
modulus carbon fiber permits the production of a mold that
is much more rigid than a conventional product, without changing
Neo-Cot refers to the ideal
tube shape derived via the finite element method. Its design
is based on such features of the optimal shape theory as the
spinning badet method to eliminate level differences inside
a tube, and the swelling of a pipe itself for lagging. The
cromoly frame of original specifications, starting with pipes
produced in-house, best illustrates the scientific approach
to Anchor design.
Hybrid refers to hybrid specifications
based on aluminum with light weight and high rigidity, and
incorporating carbon materials. It is therefore light, highly
rigid and comfortable.
The performance of a downhill
bike depends heavily on the quality of the rear suspension
link structure. What matters is computer-aided motion analysis
to translate the designer's idea into the ultimate motion.
Powder coating not only assures
a beautiful finish, but improves the paint surface strength
compared to a conventional method. This advanced painting
method helps embody images in the mind of a detail-conscious
