Smooth and silent

A bottom bracket is one of the most important parts for keeping your bike smooth and quiet. BottomFit's threaded design and self-aligning bearings help it run true in the shell, reducing the creaks that plague direct-fit bottom brackets.

Quality build

Machined from 6061-T6 aluminium with chrome steel bearings, and supplied with wave washers to set bearing preload.

Fitting

Fitting is a separate Tune Cycles workshop service, not included in the price; book at tunecycles.com.au/book.

Compatibility & fit

For BB30 (direct fit 30) frames with 68mm or 73mm shell widths and a 42mm shell bore, running cranks with a 29mm DUB spindle.
