• Outboard Bearing Bottom Brackets: These feature bearings located outside the frame, allowing for larger diameter axles and increased stiffness. Shimano's Hollowtech II and SRAM's GXP are common examples. Outboard bearing bottom brackets are widely used in modern road and mountain bikes.

Understanding these basic types is essential in determining which bottom bracket is compatible with your Fuji Track Elite.

Bottom Bracket Standards

Delving deeper, it's important to grasp the various standards within these broad categories. For instance, threaded bottom brackets typically come in two primary standards: English (BSA) and Italian. The English (BSA) standard is the most common, featuring a 68mm or 73mm shell width and a standard threading. Italian threaded bottom brackets, less common, have a 70mm shell width and unique threading.

Press-fit bottom brackets introduce even more variety. BB30 features a 30mm spindle and a 68mm wide shell, directly pressing into the frame. PF30 is similar but uses cups to house the bearings, pressing these cups into the frame. BB86/92 are commonly found on road and mountain bikes, respectively, utilizing a wider shell (86.5mm for road, 92mm for mountain) and a 24mm spindle. BB386EVO expands on this with an 86mm wide shell and a longer spindle, enhancing stiffness and power transfer.

Outboard bearing bottom brackets, exemplified by Shimano's Hollowtech II and SRAM's GXP, place the bearings outside the frame, allowing for a larger diameter spindle. This design enhances stiffness and power transfer. Shimano's Hollowtech II uses a 24mm spindle, while SRAM's GXP tapers from 24mm on the drive side to 22mm on the non-drive side.

Knowing these standards ensures compatibility with your crankset and frame, preventing issues such as play, creaking, or premature wear. Proper research and understanding are essential for a successful bottom bracket installation and optimal cycling performance.
