Magene TEO P515 Carbon Power Meter Chainset 50/34T

The Magene TEO P515 is a carbon-crank power meter chainset that pairs a lightweight HI-MOD carbon crank with a 110BCD spider-based power meter, giving racers and structured-training riders accurate power data without the weight penalty of a bolt-on system. It's built for road riders who want left/right balance, cadence and pedalling smoothness data alongside power, without paying for a premium-brand price tag.

Accurate power data in a genuinely light package

The crank arms use a HI-MOD carbon fibre construction with a dual-channel high-pressure moulding process, keeping the crank itself down to 325g (170mm) while maintaining a strong stiffness-to-weight ratio for efficient power transfer under load. The spider-based power meter is machined from 7075 aircraft-grade aluminium and adds just 99g, using strain gauges to measure power to within ±1% accuracy across a 0-2500W range, alongside cadence, left/right balance and pedalling smoothness. A 29mm aluminium spindle replaces the more common 24mm steel design, adding stiffness and waterproofing at a modest weight cost.

Features

• HI-MOD carbon fibre crank arms with 7075 aluminium spider-based power meter
• ±1% power accuracy, 0-2500W power range
• Tracks power, cadence, left/right balance and pedalling smoothness

• Total installed weight: 425g±10g (170mm crank, with accessories)

Compatibility

• Spindle standard: 29mm aluminium spindle - requires a bottom bracket compatible with a 29mm spindle. This is not a drop-in fit for standard 24mm-spindle bottom brackets; confirm your frame's bottom bracket shell and choose a compatible 29mm-spindle bottom bracket before ordering.
• Chainring interface: 110BCD, 4-bolt spider - compatible with 110BCD chainrings, including Magene's own QED chainrings
• Crank length options: 160mm, 165mm, 167.5mm, 170mm, 172.5mm and 175mm
• Chainring options at purchase: no chainring (fit your own 110BCD chainrings), or Magene chainrings in 50-34T, 52-36T or 53-39T
• Wireless protocol: ANT+ and Bluetooth - compatible with major cycling head units (including Garmin and Bryton) and training platforms (including Strava, Zwift, TrainerRoad and Magene's own Onelap/OnelapFit apps)

Magene does not publish a specific drivetrain speed rating for this chainset. Compatibility with your groupset will depend on the chainring(s) fitted rather than the crank or power meter itself - check your chainring choice against your existing cassette and chain before ordering.
