XCADEY Xpower Easton Lite Crankset Power Meter (Black)

The Xpower is XCADEY's power meter spider, sold without a crank or chainring attached, built to bolt onto an existing Easton EA90/EC90-style or compatible 110BCD 4-bolt road crank. That's the whole idea behind it: instead of forcing a rider to buy an entirely new crankset to get power data, the spider itself carries the strain gauges and electronics, and it slots onto hardware you may already own.

It's a dual-leg measurement spider with a rechargeable battery rated for 350 hours of ride time, broadcasting over both ANT+ and Bluetooth SMART so it works with a cycling computer and a phone app at the same time. Claimed accuracy is ±1.0%, and cadence is read via an internal accelerometer rather than a separate magnet and sensor.

This is the pick for a rider upgrading a crank they're already happy with, or for a shop building up a frame where the customer wants to keep a specific crank aesthetic or Q-factor while still getting real power numbers.

Why You'll Like It

Keep the crank you already have
Because the power meter lives in the spider, not the crank arm, it bolts onto a compatible existing crank (Easton EA90/EC90 or similar 110BCD 4-bolt patterns) instead of forcing a full crankset replacement.

Dual-leg power at the spider
Reads force from both legs at the point where it's transmitted into the chainring, rather than estimating one leg and doubling it.

Long runtime, dual broadcast
350 hours of battery life on a single charge, broadcasting ANT+ and Bluetooth SMART simultaneously so your head unit and your phone app both get a live feed.

Accelerometer-based cadence
Cadence comes from the spider's own accelerometer, so there's no separate magnet or sensor to fit and align on the crank arm.

Who Is It For?

This suits a rider who's already invested in a crank they want to keep - whether for fit reasons, aesthetics, or because it's a recent purchase - and just wants to add power measurement on top of it. It's also a sensible option for anyone building a bike from parts rather than buying a complete groupset.

Installation does need some mechanical comfort: it calls for a Race Face CINCH lock ring tool and a 10mm Allen key, and the brand estimates roughly an hour for the fit. For Indian riders without easy access to a specialty power meter fitter, this is worth factoring in before committing to a self-install, or budgeting for a shop's labour time.

It's a good match for structured indoor training as much as outdoor riding, since the accuracy and dual connectivity hold up equally well on a smart trainer.

Good to Know

Have a Race Face CINCH lock ring tool and a 10mm Allen key on hand before you start the install - neither is included, and both are needed to fit the spider correctly.

Confirm your chainring size before ordering a chainring separately: the spider doesn't support chainrings smaller than 34T in a 50/34 pairing, so very compact double setups (like 48/32) aren't compatible.

Pair with the XCADEY app or your head unit and run a zero-offset calibration before your first few rides to lock in consistent readings.
