Fit and compatibility

Fits a 68/73 mm BB30 shell (42 mm bore) with a 24 mm-spindle crank (Shimano, FSA and compatible). Check your frame's shell standard and width before ordering — the wrong standard will not fit.

Supplied by Tune Cycles in Marrickville, Sydney — buy online, or have us fit it in the workshop. Every hub, headset and bottom bracket service we do uses these bearings.

Manufacturing defects are covered under CEMA's warranty terms. Return the item to Tune Cycles and we will manage the claim on your behalf — you do not need to contact CEMA or the distributor. Bearings are wear items; normal wear, contamination and damage from incorrect fitting are not covered. This is in addition to your rights under the Australian Consumer Law.
