FSA Afterburner BB30 Crankset -
Hollow forged crankarms result in superior strength and stiffness and a higher strength-to-weight ratio compared to solid arms. The BB30 is lighter, narrower, stiffer and more durable than traditional bottom bracket systems. Oversized alloy spindles and bearings pressed directly into the BB shell offer weight savings up to 12%.
Please note: this crankset will only fit frames specifically built to the BB30 (new, not standard) spec.
- Chrome steel bearings, BB30 C-clips, and adjustment washers included
- AL-7075 CNC-machined Pro middle and inner chainrings
- Hollow forged AL-6061 crankarms with integrated spider
