Sram: 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, 48/35T, 50/37T Bolt Circle Diameter (BCD): Direct Mount (DM) Chainline: n/a BB Spindle Interface: n/a Chainring material: Aluminum Guard: n/a Crank arm material: n/a Color (Crank arm): n/a Power Meter Type: Spider Hub Spacing Compatibility: n/a
