Use the cranks of your choice.
Don't let yourself be limited in crankset choice. Race Face’s BB30 Bottom Bracket Adapter lets you use all Race Face, Shimano, and select FSA 24mm spindle mountain cranksets in BB30 shell frames.
The Adapter's press-fit bearing cups work like an external type headset. This positions the bearings externally with exactly the same spacing as threaded external mountain BBs. The Adapter features precision, CNC machined and anodized aluminum alloy cups, which means a more accurate, durable, and stable press-fit interface as compared with plastic molded cups.
The Race Face BB30 Bottom Bracket Adapter comes in one size and weighs 110 grams.
