About this item

Durable and Lightweight: Made of lightweight aluminum alloy material, with polished crank surface technology, providing excellent rust resistance for long-term use. Also features durable and compact wide and narrow tooth design to prevent chain drops. Strong engagement and high transmission efficiency.
Please note that these cranksets and chainrings are only compatible with single-speed setups. Please confirm the size and chainring you need before purchasing. If you have any questions, feel free to contact us.
Material: Constructed from 7075 T6 aluminum alloy, the crankset exhibits durability and sturdiness. Precise tooth shaping ensures smooth shifting performance. The high-strength detachable chainring is easy to replace and upgrade. The chromium-molybdenum steel axle, with internal weight reduction design, contributes to a lighter weight, with the entire chainring set weighing only 738 grams (including bottom bracket).
Bottom Bracket: Equipped with BB91 threaded bottom bracket, featuring built-in high-lubricity bearings. This ensures smooth pedaling action and reduced noise. Includes three aluminum alloy spacers, adding versatility.
Compatibility and Specifications: Works with 8 to 12-speed transmission systems. Suitable for wide and narrow single-speed chainrings. Hollow integrated design with BB91 threaded bottom bracket. Direct mount form, with 170mm crank arm length and 24mm axle diameter. Ideal for cycling enthusiasts and family members. Great for replacing or upgrading bicycles.
