Sram Red Axs Dub Aero (activation Required) Crankset With Power Meter. This SRAM Red AXS DUB Aero crankset is described as including an integrated power meter, but the "Activation Required" feature is a key point of consideration. Questions focus on whether this is a genuine, functional wattmeter or if it requires a separate purchase to unlock the power measurement capability. The specifics of the activation process for this high-performance aero crankset, and whether it incurs an additional cost, are common inquiries regarding its features and overall value. We're not ones to rest on our laurels. So when we found ways to make our lightest and stiffest crank even lighter, we went for it. A new process drops further grams from our hollow carbon arms, and to stay on top of current fit trends we've added our first carbon 160mm crankarm length option. Paired with an aerodynamic 1x chainring, this crank is ready to help you smash PRs.FEATURES- Single-ring drivetrain simplifies functionality and reduces weight- Direct mount aero chainrings for better aerodynamics- X-SYNC wide-tooth, narrow-tooth chainring technology provides maximum chain control- Ultra-light hollow carbon fiber crankarms are 29 g lighter than previous generation- DUB bottom bracket adds durability and simplicity- Can be upgraded to a power meterSPECIFICATIONS:- SRAM Crankset RED 1 AXS DUB 50T- BB Compatibility: All SRAM Road DUB BBs - Chainline: 45.0mm- BB Spindle Interface: DUB- Chainring material: Aluminum- Bolt Circle Diameter (BCD): Direct Mount (DM)- Crank arm material: Carbon- Power meter: No- Chain Technology: Road Flattop D1, Road Flattop E1. tradeinn Bikeinn
