Overview
Is the Kogel BB30-DUB the Best BB for Your SRAM DUB Setup?
The Kogel BB30-DUB Bottom Bracket brings ceramic bearing precision to BB30 frames running SRAM DUB cranksets, with cross seals built for durability in demanding conditions. BB30 frames are notoriously hard on bearings due to the narrow spacing between cups, making bearing quality and seal performance more important here than in almost any other bottom bracket standard. Kogel addresses this directly with ceramic bearings manufactured to tighter tolerances than standard steel alternatives, delivering less friction, better power transfer, and a smoother pedal stroke that maintains its performance over time.
The cross-seal design provides enhanced protection against contamination and moisture, extending bearing service life in varied riding conditions and making this BB suitable for year-round road riders as well as off-road use. For BB30 frame owners who have burned through multiple conventional bearings or simply want to stop thinking about their bottom bracket mid-ride, the Kogel BB30-DUB is the durable ceramic upgrade that earns its keep over the long haul. SRAM DUB spindle cranksets install directly with no adapters required.

FAQ
Good questions
Get to know Kogel
There's more to Kogel than this one product. Our Kogel page has the full Kogel lineup we carry and more about the brand.
Visit the Kogel page →Why are BB30 frames particularly hard on bottom bracket bearings?
BB30 uses a narrower bearing spacing than other standards, which increases the side load on bearings during pedaling and accelerates wear. Ceramic bearings with tighter tolerances handle these loads better and last longer than conventional steel.
Should I use cross seals on a road bike in a BB30 frame?
Yes, especially if you ride year-round or in wet conditions. Kogel recommends cross seals for BB30 road bikes because the enhanced protection extends bearing life without significantly increasing drag.
Will the BB30-DUB fit my SRAM Force AXS crankset?
Yes. This bottom bracket is compatible with any SRAM DUB spindle crankset, including Force AXS, Red AXS, Rival AXS, and GX Eagle DUB.
