104 BCD Chainring For Shimano 12-Speed

7075-T6 Aluminum is a high-strength alloy known for its durability and lightweight properties. It contains zinc as the primary alloying element, making it stronger than many other aluminum types. This material is ideal for bike components, especially in high-performance and aerospace applications, as it can withstand the rigors of tough terrains while keeping your bike lightweight.

The Drop-Stop® Tooth Design features alternating wide and narrow teeth that enhance chain retention. This design prevents the chain from bouncing off the chainring, especially on rough terrain, ensuring smoother rides and reducing the risk of chain drops. It's particularly beneficial for mountain biking, where maintaining chain stability is crucial.

Bolt Circle Diameter (BCD) is the diameter of the circle that passes through the center of the bolts attaching the chainring to the crankset. Knowing the BCD is essential for compatibility; for example, a 104mm BCD is common and allows many bikes to use the chainring without modifications. Ensuring the correct BCD means a proper fit and optimal performance for your bike.

The number of teeth on a chainring directly influences your bike's gear ratio and pedaling effort. A chainring with fewer teeth (like 32t) is better for climbing steep hills, providing easier pedaling. In contrast, a chainring with more teeth (like 36t) is suited for flat terrain and speed. Choosing the right teeth size can significantly enhance your performance based on the type of riding you do.

Wide/narrow chainrings feature a design with alternating wide and narrow teeth, which helps keep the chain securely in place. This design minimizes the chances of the chain slipping off during rides, making it especially popular in mountain biking and off-road cycling. By maintaining chain tension, wide/narrow chainrings enhance performance and safety on challenging trails.

Using a chainring with a different BCD than your crankset is not recommended, as it may not fit properly. Each crankset is designed for specific BCD measurements, and using an incompatible chainring can lead to poor performance or damage. Always check your crankset's BCD before purchasing a chainring to ensure compatibility and optimal functionality.
