Adoption of Special PinWe create a hole on both end of a pin to make the chain lightened.

Edge-Cut Inner PlateReduces friction and realizes smooth engagement with sprocket.

Precise Forging ProcessWe make our �reeD chains highly Sti�, leading to better acceleration and e�cient engine work.

LINEUP

Original Special Plate with Lightening HoleWe create a lightening hole in each inner plate without weakening the plate accordingto the computer analysis.�is plate enables the chain to be light, remove mud from the hole, and dissipate heat e�ectively.

Improvement of Transmission E�ciencyOur �reeD parts are precisely manufactured, leading to a great improvementof transmission e�ciency.

CONCEPT

ELEGANT, STRONG, DETAILED AND MAGNIFICENT,

ULTIMATE SHAPE WITH FLEXIBILITY AND STRENGTH

FIVE CONCEPTS TO MAKE OUR IDEAL THREED CHAIN A REALITY

Impressive • Ultimate Plate Shape • 3D-designed beautiful curved form is an evolutionary shape with various functions in the next generation

Dynamic • Astonishing Transmission E�ciency • Smooth and powerful acceleration by excellent transmission performance

Elegant • Bright Premium Chain • Nothing but our 3D design makes it possible to have an elegant form and everlasting beautiful light reflection

Light • Slim Design with the Minimum Weight • Produced by our exclusive technology to strengthen a chain without making it heavy

�reeD : Chains with the three “D”s Design, 3Dimension and Dynamic

Advanced • Applying Brand-new Revolutionary Process of Manufacturing • Far better than standard chains in every aspect such as fatigue strength, product quality and so on • Aiming for no Initial elongation

REDUCED FRICTION

CHROMIUM CARBIDE PIN

Non-sealed chain to reduce as much friction as possible.

Chromium Carbide pin surface coating increases hardness and reduces chain wear.

END FACING PLATE* Realizes wear-resistant performance against mud without reducing strength.

LIGHTWEIGHTPlate: Special three-dimensional plate shape strengthensa chain without making it too heavy.Pin: Both ends of the pins have lightening holes.

SX2 RINGSlim sized SX2 ring strengthens the sti�ness by reducingclearance between plates / SX2 ring has better wear-resistantperformance than SX ring by 30%.
