Como compilamos isto
Covers cycling power meters sold at a published US MSRP that measure a rider's mechanical power output in watts via a strain gauge and broadcast it to bike computers or apps. Includes pedal-based, crank-arm, spider-based, and crankset/chainring-based meters for road, gravel, and mountain bikes. Excludes indoor smart trainers, stationary-bike consoles, and estimated-power apps that infer watts without a strain gauge. Price is typical US MSRP in USD for the configuration described. mountType is the sensor form factor (pedal, crank-arm, spider, crankset, chainring, or hub). measurementSides is single-sided (one leg measured and doubled) or dual-sided (both legs measured independently). accuracyPct is the manufacturer-claimed accuracy as +/- percent, lower is better. weightGrams is manufacturer-claimed weight in grams; for pedal-based meters this is weight per pair, for crank-arm/spider/crankset meters it is added weight over the equivalent non-power component; null if not disclosed. batteryType is the cell or format used (e.g. rechargeable-liion, CR2032, CR1/3N, CR2450). batteryLifeHrs is claimed battery life in hours. connectivity lists the wireless protocols broadcast (ANT+/BLE, ANT+, or BLE). powerBalanceMeasured is true only when left/right balance is measured on both sides rather than estimated. cyclingDynamics is true when advanced pedaling metrics (torque effectiveness, pedal smoothness, power phase, platform center offset) are reported. waterproofRating is the published IP ingress rating (e.g. IP67, IPX7). warrantyYears is the manufacturer warranty length in years.
