What is the SRAM DUB PressFit Bottom Bracket 86.5mm for?

The SRAM DUB PressFit Bottom Bracket 86.5mm is designed for frames with a BB86 PressFit shell, the most common PressFit road shell standard. The DUB system uses a single oversized spindle across every shell specification, delivering better crankarm compatibility, improved element protection, and longer-lasting bearing performance. The PressFit design presses directly into the frame without threading, saving weight and providing a clean interface. Compatible with all standard DUB road and gravel cranksets.

BB86 PressFit is found on a wide range of road and gravel frames from most major manufacturers. Confirm your frame uses a 86.5mm PressFit shell (not threaded) and your crankset is standard DUB before ordering. For DUB Wide cranks, see the DUB PressFit Wide version.

FAQ

What is DUB?

DUB (Durable Unified Bottom Bracket) is SRAM's spindle standard using a 28.99mm diameter spindle, larger than traditional 24mm spindles for improved stiffness and bearing surface area. All current SRAM cranksets use the DUB interface.

What frames use an 86.5mm press-fit shell?

BB86 and BB92 press-fit frames both use 86.5mm shell width. This spec is common on carbon road frames from Trek, Giant, Specialized, and others. Confirm your frame's BB specification before ordering.

Is a special tool required for installation?

Yes. A press-fit BB installation tool (such as a Park Tool BBP-1 or equivalent) is required. Never hammer press-fit cups directly, as this can crack the bearing cups or damage the frame shell.

Best For

Road and gravel cyclists with BB86/BB92 press-fit frames running SRAM DUB cranksets who need a direct OEM-spec bottom bracket replacement.
