It uses a 24mm axle and comes with a new 24mm crank spindle and a set of spacers for 110mm and 130mm frame widths. The spindle is made of 7075 aluminum, which is both strong and lightweight, reducing rotating mass for improved pedaling efficiency.
Installation of the Cycle Engineering 710074 is straightforward. It comes with all necessary installation tools, including a press tool for installing the bearing cups, and a spindle wrench for securing the spindle. The included instructions provide clear guidance throughout the installation process.
In summary, the Cycle Engineering 710074 is a high-performance bottom bracket that offers durability, smoothness, and ease of maintenance. Its cartridge design simplifies replacement of worn bearings, while its high-quality sealed stainless steel bearings provide excellent efficiency and longevity. The included installation tools and clear instructions make installation a straightforward process, making this bottom bracket a top choice for serious cyclists.
