Running a DUB crank in a PF30 frame? BBB's BottomFit PF30-29 DUB fits straight in without adapters, and its threaded three-piece design helps keep a press-fit shell smooth and quiet.

Highlights

  • Fits 29mm DUB cranks into PF30 shells, no adapters
  • Three-piece threaded design
  • Self-aligning bearings for longer life
  • Fully CNC-machined aluminium
  • Wave washers included

Quiet press-fit, the easy way

Press-fit bottom brackets are prone to creaks when the cups aren't perfectly aligned. BottomFit's cups thread together through the shell, and self-aligning bearings take up small misalignments to increase durability.

High-end construction

The cups are fully CNC-machined from 6061-T6 and 7075-T6 aluminium and run chrome steel bearings. Wave washers are included to set bearing preload correctly.

Fitting

Press-fit shells should be clean and in tolerance before installing. Fitting is a separate Tune Cycles workshop service, not included in the price; book at tunecycles.com.au/book.

Compatibility & fit

For PF30 (press-fit 30) frames with 68mm or 73mm shell widths and a 46mm shell bore, running cranks with a 29mm DUB spindle.
