Too many bottom brackets? Here's how to find the right one

Bottom brackets are crucial components of bicycle drivetrains, connecting the bike frame to the crankset and enabling smooth pedaling motion. Enthusiasts and professional cyclists value bottom brackets for their ability to ensure efficient power transfer and maintain pedaling cadence. They come in various designs and specifications, tailored to different bikes and riding styles, whether you're tackling steep mountain trails or racing on a sleek road bike. 

When selecting a bottom bracket, there are several important properties to consider. One of the primary factors is frame compatibility, typically denoted as BSA (British Standard), which indicates the type of threading used. Ensuring compatibility with your bike frame is critical for proper fitment and function. In addition to frame compatibility, the axis diameter, commonly around 30mm, is a key consideration as it determines the size of the spindle that can rotate within the bearing. By filtering based on these properties, you can hone in on the bottom brackets that fit your bicycle’s requirements and your cycling goals.

Top brands in bottom brackets include BBB, Race Face, Shimano, Sram, and Ceramicspeed. BBB offers options such as the OEM bearing BB30 Ø42/30 x 7mm SRAM 20x, known for robustness. Race Face’s Cinch bottom bracket BSA 73mm External Seal AM19 is a popular choice for riders seeking durable external configurations. Shimano delivers reliability and efficiency with their Ultegra SM-BBR60, a favorite among road cyclists. Sram’s DUB Pressfit Road bottom bracket combines innovation with ease of installation, while Ceramicspeed’s BSA30 MTB Black coated stands out for its superior performance and longevity, particularly appealing to mountain bike enthusiasts. 

With a wide selection to choose from, you can find the perfect bottom bracket that fits your cycling needs, enhancing your riding experience.
