Durable QX-Ring Chain
The DEX series is a budget friendly sealed Quadra X-Ring (QX-Ring) chain. QX-Ring provides 1.5-2x longer chain life!

Quadra X-ring (QX-Ring) is a slim profile chain with 40% less friction than a normal O-Ring chain and 150% better endurance. Used for a variety of SRX2, 420SRX and 428ZVX series chains.

Supersprox Front Sprocket

Supersprox countershaft sprockets are factory-team spec parts (used in WSBK, MXGP, and Rally) made from ultra-durable, carbon-impregnated SCM-435 (18HGT) steel for maximum strength. They feature a lightened design with radial holes or slots, an ultra-hard surface layer to reduce chain friction, a black oxide coating to prevent corrosion, and self-cleaning grooved teeth on off-road models to extend chain and sprocket life.

Supersprox Aluminium rear sprocket

Used in racing since 1959, Supersprox Aluminum Rear Sprockets are the ultimate choice for maximum weight savings. Precision CNC-machined from world-class 7076-T651 aluminum, they feature a special tooth design and mud-clearing grooves to extend chain and sprocket life, finished with high-quality durable anodizing in various colors.
