SRAM's DUB bottom bracket system solved a compatibility headache that had been getting worse for years — every frame brand seemingly picking a different press-fit standard while cranksets were locked to specific spindle diameters. The DUB DUB BBRight PF30 79-A Road Bottom Bracket is the version built for BBRight frames with the 79mm shell width and 46mm inner diameter, which shows up on Cervélo road frames and a handful of other press-fit designs using that standard. It's the piece you need if you want to run a SRAM DUB crank on a BBRight bike.

The whole point of DUB is that SRAM's DUB cranksets use a 28.99mm spindle across the board, allowing you to upgrade your crank while future-proofing it against changing BB standards . That spindle diameter sits between the traditional 24mm GXP standard and the 30mm PF30 crank spindles, and SRAM's argument is that instead of matching the crank spindle to the frame shell, the crank uses one universal spindle and the bottom bracket cups adapt to whatever frame you have. In practice, that means the same Force, Rival, or Red AXS DUB crankset works on threaded, PressFit, or BBRight frames — you just swap the bottom bracket.

Confirm your shell measures 79mm wide with a 46mm inner diameter before ordering. BBRight has appeared in multiple widths over the years, and this specific version (the 79-A) is the road-width option. If your frame is the wider 83mm BBRight variant, this same bottom bracket covers it — SRAM builds the two widths under the same part number.
