Hollow Integrated Crank Axle Modified Single Disc Crank for Mountain Bike

Product Description: The mountain bike hollow integrated chainring offers a cost-effective and efficient solution, featuring an integrated crank axle design that provides high strength and a more labor-saving riding experience, with faster acceleration. The axial chromium molybdenum steel construction improves the stability and performance of the cranks and hollow shafts.

The wide tooth and narrow design of the chainring significantly increases the contact area with the chain, allowing each tooth to be fully inserted and providing enhanced grip, thereby eliminating concerns about the chain falling off and enabling easy traversal of rough terrain. The internal weight reduction design contributes to a lighter crank weight.

The key advantages of the hollow one-piece chainring crank include its lightweight aluminum alloy construction, stylish appearance, high shaft strength, and strong compatibility. The hollow integrated crankset crank features the following specifications:

Crank: 170MM Material: Aluminum Alloy Specification: BCD 104 Weight: A set of left and right cranks weighs 675g

The aluminum alloy construction not only reduces the overall bicycle weight but also offers high strength and corrosion resistance. The elegant appearance and ease of cleaning effectively protect the bicycle frame and prevent scratches.

The 104 BCD ultralight mountain bike crank is designed for single-speed chainrings only, with a crank arm length of 170mm and a crank weight of 550g. The crank-related hole distance is 74mm.

The chainring is a snail single-speed narrow-wide teeth design, with a 104BCD and available in 32/34/36/38T options. The chainring thickness is 4mm, with narrow teeth measuring 1.9mm and wide teeth measuring 3.7mm, weighing approximately 45g.

It is important to note that these crank and chainring components are only suitable for single-speed applications and cannot be used with other gear configurations. If you have any questions before or after purchase, please feel free to contact us.
