Built from premium materials and engineered for consistent performance in all conditions, it delivers accurate data, smooth power transfer, and broad compatibility for modern road bikes.The crankset features a triple-hollow channel design, cnc machining, and deep-hole drilling to reduce weight while maximising structural strength. After 100,000 cycles of harsh pedalling tests, the system maintains its stiffness and reliability. The spider itself is crafted from 7075 aircraft grade aluminium, weighing only 99g, balancing low weight with exceptional rigidity.The p515 provides four essential cycling metrics, power, cadence, left right balance, and pedalling smoothness, allowing riders to analyse their technique and training efficiency in detail. With an impressive 330-hour battery life, it supports long-distance training and multi-day rides without frequent charging. 1% Power accuracy, capture your every effort accuratelythe p515 spider-based power meter employs high-precision strain gauges and acceleration sensors. Combined with built-in intelligent temperature compensation algorithms, it can provide precise and reliable power data anytime and anywhere, even when the environment changes constantly. Extensively tested in harsh environments with highly demanded standards, and with each strain gauge undergoing stress release, the product guarantees a 1% power accuracy, never letting your effort in vain.4 Essential cycling data: evaluate your cycling ability comprehensivelypowe...
