CNC-machined aluminum refers to aluminum parts that have been precisely cut and shaped using computer-controlled machines. This process ensures high accuracy and quality in the design, resulting in lightweight yet durable components. Choosing CNC-machined aluminum for your bike means you’re investing in parts that enhance performance and longevity.

BB392EVO is a specific bottom bracket standard that defines the dimensions and design features for compatibility with certain cranksets and frames. Using a BB392EVO bottom bracket ensures a proper fit, which is crucial for smooth pedaling and overall bike performance. It helps maintain the bike's efficiency and responsiveness.

The Q factor is the distance between the outer edges of the crank arms. A Q factor of 169mm provides a specific width that can influence your foot positioning while pedaling. A wider Q factor can enhance stability, while a narrower one allows for a more natural leg movement. Choosing the right Q factor can improve your comfort and efficiency during rides.

Chainline refers to the alignment of the chain with the chainring and rear cog. A proper chainline, like the specified 51.8mm, ensures that the chain runs smoothly, reducing wear and improving shifting performance. A well-aligned chainline enhances your bike's efficiency, making your rides more enjoyable and hassle-free.

Boost 148mm spacing refers to the width of the rear hub on a mountain bike, which is designed to be 148mm wide. This standard allows for wider tires and improved wheel strength, enhancing stability and performance on rough terrain. If you're looking to tackle challenging trails, Boost spacing is a great feature to consider for better handling and control.

Each of these features—CNC-machined aluminum, BB392EVO bottom bracket, Q factor, chainline, and Boost 148mm spacing—contributes to the overall performance of your bike. Together, they ensure precision, compatibility, comfort, and stability, allowing for a smoother and more efficient ride. Investing in a bike with these specifications means you're choosing a high-quality, performance-oriented machine.
