FSA PowerBox – Unleash your power

The FSA PowerBox 1-speed crankset for Road and Gravel bikes employs a convertible spider design for multiple chainring options. The aluminium version is very attractively priced providing nevertheless consistent and reliable performance.

Powermeter cranks represent a fundamental tool helping riders to track their data directly during training sessions and to be increasingly more competitive on race day. With an accuracy of +/- 2 %, precision is the key quality of the PowerBox Alloy crankset. Its spider-based power sensors provide a total power output and cadence measurement of both legs.* The data is transmitted via Bluetooth.

Cold forged crank arms made of aluminium 6061-T6 and a BB386EVO spindle made of aluminium 7050 are mated together producing a very light, extremely versatile Powermeter crank. Combined with the appropriate bottom bracket, the 30 mm axle is compatible to almost any frame type.

The chainring in Stealth Black is made of CNC-machined aluminium 7075 and optimized for 11-speed shifting systems. Its MegaTooth profile with very long, asymmetric teeth in a thick-thin alternation creates a tremendously quiet and secure engagement providing a safe chain retention also when the chain is tilted or the weather turns bad. In addition, the proven ABS system (Asymmetric Bolt Spacing) with strategically positioned chainring bolts increases stiffness.

* Via optional system updates you can buy more features like a separate left and right leg output analysis as well as a pedal smoothness upgrade.

MegaTooth

The teeth of MegaTooth chainrings are longer than standard with an asymmetric profile shape, a diamond-shaped cross-section and a unique system of alternating thick then thin teeth. This allows for smooth chain engagement, meaning that the chain always remains in close contact with the chainring to give you the most reliable and positive drive possible.
