EK SP/3D

The pin and roler have been treated with OX-FPS processing to reduce friction. 520SP is a high-spec model chain designed to win races.

EK Chain set out to produce a premium chain that was as beautiful as it is strong.  An impressive outer plate shape that offers a curved form to reduce weight and increase appeal is connected together with inner plates and pins that feature lightening holes to further reduce mass.

• 200 g lighter than most any other current high performance chain
• 520 chain has 9,400 lb tensile strength
• The exclusive SX2 Ring leads to 30% reduction of friction (compared with our exsisting products).
• Chromium Carbide pin surface coating increases hardness and reduces chain wear.
• Our ThreeD parts are precisely manufactured, leading to a great improvement of transmission efficiency.
