The 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.
625g Light-weight and High-stiffness Design, Unleash Your Power Hard
The PES crank adopts a triple hollow channel design. The extensive hollow spaces reduce weight greatly. The crank is integrally molded by applying precise CNC with deep-hole drilling techniques. While optimizing the sealing technique, the force structure is completely enhanced with a symmetric design. The weight is reduced greatly yet without affecting performance. After 100,000 times of harsh pedaling, it still performs excellently.
The P515 spider-based power meteris made of 7075 aircraft-grade aluminum. The selection of premium materials balances the weight while achieving great stiffness, making the power meter weighs 99g only.
