The Box One Two Oversized, External, Square-Taper Titanium/Chromoly BMX Bottom Bracket is an innovative solution designed for serious BMX riders who demand the best performance from their bikes. With a size of 68/73mm x 24mm, this bottom bracket has been meticulously engineered to provide optimized power delivery, enhanced stability, and exceptional efficiency during rides.

One of the standout features of this bottom bracket is its Oversized Technology, developed through collaboration with our crank sets. This technology maximizes power transfer from the pedals directly to the rear wheel. By enlarging the spindle and crank arm interfaces, the Box Bike Bottom Bracket significantly enhances pedaling stiffness. As a result, the energy you exert is translated efficiently into forward momentum, allowing for a more responsive and powerful riding experience.

Furthermore, the bottom bracket is designed to minimize lateral deflection. It achieves this by accommodating larger bearing rings, which significantly increase the contact area. This structural enhancement not only stabilizes your ride but also improves the responsiveness of acceleration, requiring less energy for the same distance covered. Whether you’re racing or enjoying a casual ride, you’ll notice the difference in performance.

The construction of the Box Two M30 Bottom Bracket is another highlight. It is crafted from forged and CNC-machined alloy cups, complemented by an ABS plastic sleeve. This durable construction is further enhanced by a hard anodized finish, ensuring longevity and resistance to wear and tear. You can trust that this bottom bracket will withstand the rigors of BMX riding while maintaining its performance characteristics.

In terms of performance, the Box Two M30 Bicycle Bottom Bracket embodies a slightly less acute version of our Oversized technology found in the M35 model. It utilizes ABEC-5 bearings that are generously sized to reduce power loss through deflection, ensuring that every pedal stroke counts. You’ll experience extreme oversized performance that elevates your riding experience and gives you the edge you need.

Additionally, the Box Two M30 BMX Bottom Bracket features premium elements such as an oversized technology with a large diameter for enhanced stiffness and a stable outboard bearing position. The larger 30mm cross-section is specifically designed to interface seamlessly with the other components in the M30 line of oversized cranksets. This compatibility ensures that you can maximize the performance of your bike with ease.

As a replacement BSA bottom bracket for Box Two M30 cranks, please note that this bottom bracket is specifically designed to work with Box Two M30-P, M30-M, or other Praxis M30 cranks only. This ensures that you are getting the right fit and performance for your particular setup.

In conclusion, the Box One Two Oversized, External, Square-Taper Titanium/Chromoly BMX Bottom Bracket is a top-of-the-line component for any BMX enthusiast. Its combination of optimized power delivery, enhanced stability, and durable construction makes it an essential part of your bike setup. Upgrade your ride today and feel the difference in performance!
