Hope BB Conversion Kit 1 — SRAM DUB 29mm to BSA / PF46 / T47 68/73 | Black

SRAM DUB cranks use a 29mm spindle. Hope bottom brackets — BSA, PF46, and T47 — are designed around a 30mm spindle bore. That 1mm gap is where this kit comes in.

The Hope BB Conversion Kit 1 is the precision machined aluminium adaptor set that bridges the difference between SRAM DUB’s 29mm spindle and Hope’s 30mm bottom bracket spindle bore — letting you run SRAM DUB cranks in a Hope BSA, PF46, or T47 bottom bracket without noise, play, or compromise.

Rugged aluminum construction means these adaptors will last as long as the cranks are in the bottom bracket, and precision machining ensures a tight and noise free installation.

What’s in the Kit

Includes two bottom bracket spindle adaptors (for each side of the bottom bracket), one 1mm spacer for SRAM road cranksets, and one 2mm spacer for SRAM MTB/Wide Gravel cranksets.

• 2x spindle adaptors — one for the drive side, one for the non-drive side; sleeve the SRAM DUB 29mm spindle to fit the Hope 30mm bore
• 1mm spacer — for SRAM road crankset applications
• 2mm spacer — for SRAM MTB and Wide Gravel crankset applications

Key Features

Construction

• Machined aluminum construction to very tight tolerances to eliminate noise and play in the crank/bottom bracket interface
• Black anodised aluminium — consistent with Hope’s full colour range for a clean, coordinated install
• Precision bore dimensions ensure a creak-free, rattle-free interface between spindle and bottom bracket across the full life of the drivetrain

Compatibility

• Adapts SRAM DUB cranksets with a 29mm bottom bracket spindle to fit inside of a Hope BSA (68mm to 83mm shell width), PF46 (68mm to 83mm shell width), or T47 (with a 68 or 73mm shell width) bottom bracket with a 30mm diameter spindle hole
• Spindle interface: SRAM DUB
• Not compatible with non-DUB SRAM cranksets or other 29mm spindle standards — verify your crankset uses SRAM DUB before ordering
