C-Bear is a Belgian company that makes ceramic bearing bottom brackets, all with a 2-year warranty on the bearings. The Lotto pro team’s been racing them on the road, and there’s also a mountain bike bearing that’s more waterproof which Niels Albert rode for an entire season with no issues.
The company was started because they wanted something that would roll smooth and last longer, so they pack in more grease, using different seals and lubricants depending on the intended application. To make them stronger and fit better, they’re available for virtually every crankset on any bike without adapters. That reduces the number of parts used, particularly for combinations like Shimano cranksets on BB30/PFBB30 frames. Same for BB386, PF86, BB90, BBright, etc.
They’ve been around in Belgium since 2008, and they’ve started distributing in the US in December 2012 through Ard Kessels, owner of Sprocket Scientists.
