Sram: It looks like it’s from the future, but it’s here now. Our lightest, stiffest, and most accurate integrated power meter and chainring combo is now on Force. Quarq D-Zero technology is accurate to +/-1.5% and isn’t affected by temperature changes, and the consistent 13-tooth gap on the rings ensures fast and reliable shifting. Not just unbeatable on performance, our integrated rings are also incredibly long-lasting. And let’s not be modest: the combination of these rings on our iridescent carbon crankarm is the best looking thing out there.FEATURESX-Range gearing technology gives you more range and a smoother gear progression, so you’re always in the right gearPower meter is fully integrated into the chainring set for lighter weightPower readings are accurate within +/-1.5% and aren’t affected by climate conditions during a rideMeasures right and left leg power balanceUnique chainring shape results in a lighter weight, stiffer, more durable cranksetDUB bottom bracket adds durability, simplicity and broad compatibility SPECIFICATIONSSpeeds: 12BB Compatibility: All SRAM Road DUB BBsChainring Size: 48/35TCrank arm length: 165mm, 167.5mm, 170mm, 172.5mm, 175mm, 177.5mmChainline: 45.0mmBB Spindle Interface: DUBChainring material: AluminumGuard: No GuardBolt Circle Diameter (BCD): Direct Mount (DM)Crank arm material: CarbonColor (Crank arm): IridescentPower meter: YesPower Meter Type: Spider
