Features:
1. Fully hollow and lightweight design, lightweight and practical
2. Full CNC cutting, strong and durable
3. Thicker disc, better rigidity
4. Positive and negative tooth design, not easy to drop the chain, arc transition of the connection position, not easy to accumulate sand
5. Easy to install
Description:
1. The larger the number of teeth of the disc, the larger the diameter, the faster the relative riding, and the harder it will be
2. When choosing a disc with a large number of teeth, please make sure that its diameter will not rub against the frame, otherwise you need to replace a longer bottom bracket
3. Change the large number of teeth disc, the chain must be lengthened
4. Please make sure that the BCD is 130 mm
5. BCD is the circle surrounded by 5 holes of the crank. The diameter of this circle is 65mm from the crank hole to the crank center. (Note the distance on the plane on the side of the chainring)
