Home Bottom Brackets

Bottom Brackets

Bottom brackets are essential to drivetrain efficiency—supporting your crankset and keeping power transfer smooth and quiet.

Colorado Cyclist carries bottom brackets from trusted brands like Shimano, SRAM, PraxisWorks, and Chris King, covering popular threaded and press-fit standards. A high-quality bottom bracket reduces friction, improves durability and power tansfer through your crank and frame.

Replacing a worn bottom bracket is a simple upgrade that restores smooth pedaling and long-term reliability.
