The EK-01 is a spider-based power meter that mounts directly onto Easton Cinch-compatible interfaces such as Elilee's own cranks.

At 96g for the aluminium version, it is among the lightest spider power meters at this price point, with a full data suite and a 300-hour battery life.

The 4-bolt 110 BCD pattern is compatible with the full range of Shimano-standard chainrings, including third-party options from Absolute Black, Wolf Tooth, and others.

Dual ANT+ and Bluetooth means it can pair simultaneously with a head unit and a training app.

Features

Easton Cinch Direct Mount

Bolts directly to Elilee cranksets (X310 and compatible models) without adapters.

4-Bolt 110 BCD: Shimano Chainring Compatible

The same standard used across Shimano Dura-Ace, Ultegra, and 105 chainrings. Any 110 BCD 4-bolt option fits.

±1% Accuracy with Automatic Temperature Compensation

Strain gauge calibration adjusts automatically as spider temperature changes throughout a ride, keeping readings consistent without manual zero resets.

After installation, perform a zero-offset per device instructions

Power, Cadence, and Left/Right Balance

Covers 0 to 2000W power range and 0 to 200 RPM cadence range. Left/right balance data is useful for identifying asymmetrical pedalling patterns and monitoring fatigue or fit issues over time.

300-Hour Battery with Magnetic Charging

Roughly six weeks of riding at 10 hours per week between charges. The magnetic cable attaches cleanly to the spider body with no port covers to deal with.

IP67 and Dual Connectivity

IP67 rated for dust and rain protection. Simultaneous Bluetooth and ANT+ transmission supports two devices at once. Firmware updates via the Elilee app.
