ZF two sprockets are among the highest quality and most technologically advanced sprockets in the world.
The secret lies in the connection of the strength of steel and the ease of duralumin.
This aluminum alloy is characterized by enormous strength and rigidity, as well as light weight.
The tensile strength is about 11 times of pure aluminum.
By hardening duralumin almost reached the strength of steel.
implemented is therefore a lower weight and greater durability.
Grinding at the base of the tooth of the chain wheel ensure optimal self-cleaning.
These millings ensure that dirt cannot start between the teeth and therefore the chain and sprocket do not wear out as quickly.
The durability of the IF double sprockets is approximately three times more than pure aluminum sprockets and they are 50% lighter than steel sprockets.
Ideal for highway and off-road. DIVISION: 520 INSIDE DIAMETER: 63MM CIRCLE SIZE: 110 MM HOLE: 8.5MM HOLES QUANTITY: 6 SCREW TYPE: FLAT HEAD QTY TEETH: 43 CROWN TYPE: DUAL
