From NYB:
The beginnings of Nankai
Nankai Tekko KK, Techno Nankai was established
in 1923 in Hamamoto
cho, Sumiyoshi-ku, Osaka, Japan as a bicycle parts
factory. We focused
especially on coaster brake hubs and exported them mainly
to the
South-East Asian region. Since 1959, we exported our coaster
brake
hubs to USA; a major consumer in the world. We were the very
first
Japanese bicycles parts company to do so. The top 3 coaster brake
hub
manufacturers at the time were, Torpedo (Germany), Bendix (USA)
and
Nankai (Japan). Nankai has been renamed and is now known as
NYB.
What are major features of the new hubs?
The major feature is
the angular bearings that reduce friction and
maintain speed even when the
axle is slanted at a 30 degrees angle.
Commonly used radial bearings are not
designed for that use. In the
case of BMX riding, radial bearings will wear
down rapidly and they
are unadjustable. Although our coaster hubs require
adjustments before
use, we have known users who have ridden them for 20
years.
What has been improved from the old
hub?
First, the clutch’s reliability has been improved to prevent
cranks
from catching while coasting backwards. Secondly, the weight has
been
reduced. The new FCH-K-MX3/8 hub is 100 grams lighter compared to
the
AKA3/8 hub. While the new FCH-B-MX14mm hub is 44 grams
lighter
compared to the ABA14mm hub. All axles are cr-mo. Lastly, there are
no
backwards compatibility for the latest hubs except for some
parts.
We’ve tried to keep backwards compatibility for the past 20 years
but
huge improvements with the latest hub unfortunately didn’t allow us
to
do so.
