Aluminum alloy one-piece forging: mountain bike chainring, the disc is aluminum alloy, CNC cutting technology, one-piece forging processing is completed, not easy to rust and deform;
Not only beautiful appearance, but also high wear resistance, not leaking, special structure design has high strength and life.
Anodic sandblasting treatment: Anodizing will generate an oxide film on the surface of aluminum, which not only has a good texture, but also effectively protects the aluminum alloy body, preventing corrosion and rust.
The anodized surface uses sandblasting technology, fine sandblasting, fine texture, long-term use does not fade, and more durable.
Single disc to reduce chain loss: CNC high-speed engraving and milling + hard oxidation treatment, the gears are neat and symmetrical, the unique inclination angle and the uniquely shaped mud discharge oblique mouth and the chain are highly overlapped, and the bite is fixed and stable and weight-reducing treatment.
Body material: aluminum alloy
34T, Outer diameter 144mm, net weight about 50g;
36T, Outer diameter 153mm, net weight about 61.3g;
38T, Outer diameter 161mm, net weight about 81g
Applicable crank: 104BCD (the diameter of the circle formed by the center points of the four nail holes is 104mm)
Advantages of chain ring: remove the front derailleur, greatly reduce the load on the vehicle, and keep the chain on riding
1. The sprocket BCD is 104, and the purchaser carefully determines that his crank is 104BCD (the diameter of the circle formed by the center points of the four disc nail holes is 104 mm), do not make a mistake, or it will fail to install.
2. The disc nail holes of this disc are designed without countersinks, and the disc nails can directly use the three and second disc nails of the chainring to be modified, without the need to purchase a single disc nail.
The price of this disc does not include disc nails, please purchase separately if you need it.
