Crankbrothers

Crankbrothers is a privately held company specializing in the design, manufacturing, and distribution of high-performance bicycle components, particularly known for its cranksets and bottom brackets. Founded in 2006 by former Trek Bicycle Corporation engineer and inventor, Mike Sinyard, the company is headquartered in San Jose, California. Crankbrothers is recognized for its innovative engineering and commitment to improving cycling efficiency, comfort, and performance.

The company’s most notable product line includes the *Crankbrothers PowerBar* and *PowerBar Pro* cranksets, which feature a unique design with a single central spindle and a floating chainring system. This design eliminates the need for a chainstay to hold the crankset in place, reducing weight and improving pedal stroke efficiency. The company also produces the *Crankbrothers PowerBar Pro* and *PowerBar Pro 2* models, which incorporate carbon fiber construction for enhanced stiffness and reduced weight.

Beyond cranksets, Crankbrothers offers a range of accessories, including chainrings, pedals, and bottom brackets, designed to complement its core products. The company emphasizes durability, precision engineering, and compatibility with various bicycle types, including road, mountain, and gravel bikes. Crankbrothers components are widely used by professional cyclists, teams, and enthusiasts seeking high-performance solutions.

The brand has gained a reputation for its technical innovation and collaboration with cyclists and engineers to refine its products. While primarily focused on performance cycling, Crankbrothers components are also appreciated for their reliability and unique design aesthetics. The company operates under a business model that prioritizes quality and customer satisfaction, though it remains relatively niche compared to larger bicycle component manufacturers.
