The Magene TEO P515 is a dual-sided, carbon, spider-based road power meter chainset with HI-MOD carbon crank arms, a 7075 aluminium P515 spider and a 52/36T 110 BCD chainring set ready to bolt on. At 425 g for the full system - around 200 g lighter than the alloy PES sibling - it's the lightweight, race-focused option in the line, and the 29 mm 7075 aluminium spindle drops straight into most SRAM DUB-style frames. 1% accuracy, 330-hour battery life and broad ANT+/Bluetooth compatibility seal the deal.
