Train and pace with power by swapping the spider on your Easton Cinch crankset. The COOSPO S10 measures power at the spider, so your existing crank arms stay and your 110 BCD chainrings bolt straight on.

Highlights

  • Fits cranks with an Easton Cinch interface
  • 110 BCD, 4-bolt chainring mount
  • 0 to 2800W range, plus or minus 1% accuracy
  • Power, cadence (20 to 240 rpm), left-right balance and pedalling smoothness
  • ANT+ and Bluetooth
  • 300-hour battery with magnetic charging, IPX7
  • 7075 aluminium alloy, 102g

Power at the spider

The S10 sends data to your head unit or app over ANT+ and Bluetooth, and COOSPO's CoospoTools app handles set-up. Calibration is automatic, with backpedal and manual options too. It's machined from 7075 aluminium alloy, rated IPX7 and works from -20 to 50°C.

Compatibility & fit

COOSPO lists the S10 for cranks with an Easton (Cinch) interface, including Easton EA90 and EC90 SL and other cranks with a detachable Easton-interface spider. It takes Shimano 110 BCD 4-bolt chainrings (105, Ultegra, Dura-Ace), but COOSPO notes it doesn't fit Shimano 105, Ultegra or Dura-Ace cranks, whose spider is integrated. Chainrings are not included. In the box: S10 unit, charging cable and user manual.

Our workshop can install the spider, fit your chainrings and pair it with your head unit.

COOSPO backs this product with a 1-year warranty against manufacturing defects. For warranty support, return the product to Tune Cycles and we'll manage the claim with KWT Imports, COOSPO's Australian distributor.
