It’s the ultimate in integrated power measurement. The Force AXS power meter kit adds Quarq technology to our one-piece chainrings for the lightest, stiffest, and most accurate power package available. A 13-tooth delta on all chainring pairs ensures precise shifting for any setup, as well as a less dramatic change in cadence during front shifts. Combined with our most durable chainrings ever, it’s an unbeatable combination. Features X-Range gearing technology gives you more range and a smoother gear progression, so you’re always in the right gear Power meter is fully integrated into the chainring set for lighter weight Power readings are accurate within +/-1.5% and aren’t affected by climate conditions during a ride Measures right and left leg power balance Crisp and accurate front shifts Unique chainring shape results in a lighter weight, stiffer, more durable unit Specifications Speeds 12 Crank arm length n/a BB Compatibility n/a Chainring Size 46/33T Bolt Circle Diameter (BCD)Direct Mount (DM) Chainline n/a BB Spindle Interface n/a Chainring material Aluminium Guard n/a Crank arm material n/a Colour (Crank arm) n/a Power Meter Type Spider Hub Spacing Compatibility n/a
