Product Description

The Shimano BB-UN300 British Thread 73/113mm Bottom Bracket is a reliable replacement bottom bracket for traditional square taper chainsets. It uses a sealed cartridge bearing assembly to help protect the bearings from dirt, mud, and water. Super-accurate bearings support smooth crank rotation, while the hard-wearing build gives dependable performance over regular use. Its narrow body also helps give clearance for cable routing under the bottom bracket.Key Features and Benefits:Sealed cartridge bearing assembly: The cartridge design helps keep dirt, mud, and water away from the bearings. This reduces the need for maintenance and helps the bottom bracket keep running smoothly for longer.Super-accurate bearings: The bearings are made to support smooth and consistent rotation. This helps reduce roughness through the pedals and gives the chainset a more stable feel during use.Square tapered spindle fitting: The square taper interface suits traditional chainsets that use this proven fitting system. This makes it a practical choice for repairs, upgrades, or like-for-like replacements.Durable, hard-wearing construction: The bottom bracket is built for regular use and long service life. This helps maintain dependable support for the crankset over time.Fast and easy installation: The sealed cartridge unit fits without bearing adjustment. This makes fitting simpler and helps reduce setup time.Narrow body design: The compact body helps create clearance for cable routing under the bottom bracket. This supports a cleaner fit on frames where cable space is limited.A smooth, reliable bottom bracket helps the drivetrain feel more direct and consistent. The BB-UN300 supports this with sealed bearings, a strong cartridge design, and simple fitment. It is well suited to bikes that use a British threaded bottom bracket shell and a square taper chainset.Choose the Shimano BB-UN300 British Thread 73/113mm Bottom Bracket for a dependable replacement that is easy to fit, low maintenance, and built for steady long-term use.Specification:Size - 73 - 113mmBottom Bracket Type - BSA ThreadedWidth -73 mm
