This exceptional product comes with both chainrings and a bottom bracket, offering you a complete and hassle – free installation experience.

The chainrings are crafted from 7075 aluminum alloy through precision CNC machining. This high – grade aluminum alloy not only provides remarkable strength but also ensures a lightweight design, which is crucial for enhancing the overall performance of your bike. The CNC machining process guarantees high precision and smooth surfaces, allowing for seamless chain movement and efficient power transfer.

The crank length is precisely set at 170mm, a popular choice among cyclists as it provides an optimal balance between power transfer and pedaling efficiency. It suits a wide range of riders, whether you’re a professional racer or a casual cyclist.

The chainrings feature a tooth configuration of 34T – 50T. This combination gives you a versatile gear ratio, enabling you to easily tackle various terrains. When climbing steep hills, the 34T small chainring provides the necessary low – gear for smooth and steady ascents. On flat roads or when you want to pick up speed, the 50T large chainring allows you to generate high power and reach impressive velocities.

The cranks are made using 3D forging technology, which creates a strong and robust structure. After forging, they undergo CNC finishing to ensure precise dimensions and a refined surface finish. This combination of 3D forging and CNC finishing results in cranks that are not only incredibly strong but also aesthetically pleasing.

Crafted with top – notch materials and advanced manufacturing techniques, this double – chainring crankset ensures durability, reliability, and excellent performance. It’s the perfect upgrade for your road bike, enhancing your cycling experience to a whole new level.
