An ultralight chainring set featuring a sandwiched carbon/alloy outer ring with a full aluminium inner ring. The carbon hybrid sandwiched design of the outer ring provides for a lightweight yet stiff chainring but with the durability of metal teeth. The chainrings are slightly thicker than the usual chainrings which leads to stiffness but requires slightly longer chainring bolts.
- The 5.9mm thick structure leads to a firmer and stronger product
- The combination of high modulus carbon fiber and ultra light 7075 aviation grade aluminum is perfect
- The high modulus carbon fiber provides superior lateral and driving rigidity and helps reduce weight
- Compared with the traditional aluminum sprocket blade, the weight is reduced and the rigidity is increased by 31%
- The optimised tooth profile provides a fast and accurate gear shifting experience
