Description

Special Small Plastic Dual Gear 16mm For Derailleur Corrosion Resistance

Plastic dual gears with special design for derailleur , a pin socket hole in the centre of small gear , four supporting beams are placed between pin hole and small gear .

Dual gears with a double different reference circles gears so that meet different speed requests under same power feeding , both gears have a same modulus .

Material

Duplex gears are made from plastic ABS
