Sturdy Structure: oval chainring is made of high-strength aluminum alloy, which is good at resisting pressure, anti- and wear-resistant, and not easy to break or deform.
Design: The oval chainring is designed with narrow and wide teeth, so that the narrow and wide teeth of the disk overlap with the outer and inner chain, which ensures better chain retention and reduces friction and noise.
Stable Performance: CNC cutting and integral can provide smoother ride and better climbing ability, which greatly improves riding efficiency
Compatibility: The 54T chainrings are made of 110 BCD/130 BCD, compatible with most bikes. The hardware for riding your folding in all terrains and conditions.
Ideal Accessory: Easy to install and adjust to improve the riding performance of 7 8 9 10 speed road folding bikes, a great choice for cycling beginners and enthusiasts.
