SUGINO CBB-AL Bottom Brackets

Assemble a slender, beautiful steel frame with the classical, sophisticated square-taper crankset that only Sugino can provide. For such a timeless and high-quality bike build, Sugino's high-end "CBB-AL" bottom bracket works from out of sight to elevate your ride to excellence.

Among cartridge-style square-taper BBs, which tend to be heavy, this model luxuriously adopts machined, lightweight aluminum cups. While achieving a significant reduction in weight at your feet, the anodized cups, visible when screwed into the frame, enhance your satisfaction with your custom bike down to the smallest detail.

Of course, world-class Sugino quality truly resides in the smoothness of its rotation.
Inside, it features high-precision sealed bearings that have cleared the most rigorous European "EN standard" racing criteria. While boasting high durability to thoroughly prevent the ingress of muddy water and sand, it maintains that exquisite pedaling feel for a long time—the sensation of the crank spinning as if being sucked into motion.

Because it utilizes the JIS standard (JIS 4-taper) square axle, it is widely compatible with various JIS square cranks, including the classic Sugino "RD" and "Messenger" series, as well as Shimano cranks.

With a rich lineup of axle lengths, from achieving a perfect chainline for single-speed (fixed gear) bikes to building front double or triple road and touring bikes, this is a masterpiece BB packed with the pride of a Japanese brand—a choice for cyclists who want to perfect their bike as a "tool for life."
