BBinfinite already makes some of the smoothest bottom brackets on the market thanks to their one-piece shell design that ensures perfect alignment of the bearings. Even so, they offer a Ceramitech ceramic bearing upgrade there, and now they offer it for Mavic and DT Swiss hubs, too. They can’t control the shell they’re going into, but the bearings get a chrome steel races that get special finish polishing before they’re loaded with ABEC-5 level ceramic bearings inside.
Their first bearing sets are available for Mavic and DT Swiss hubs, and they claim they’re good for saving 7-9 watts. That should buy you a few extra seconds. Use their online selector to find the right bearing set for your wheels on their website. For now, your options are DT 240s, and Mavic Ksyrium SR/SL, Cosmic SL, R-Sys and Carbone, . Retail is $275, available now.
