This superb model is fully compatible with the new Shimano 96mm BCD cranks. Featuring an alternating 1.8/3.5mm width tooth profile, which interlocks with the chain for ultimate security, with no loss of efficiency. What's most impressive is the increased mud clearance thanks to the reduced frontal profile of the 3.5mm wide teeth. Made from hard wearing 7075 T6 aluminium which also benefits from a hard-anodised surface treatment for even further durability. Finally, this dazzling model shows off mud evacuation grooves in the tooth bed for smooth & reliable performance.
