What it does well
- It is the only dual sided power meter on the Speedplay platform, so for riders committed to those cleats there is no alternative that does not mean changing shoes and cleats.
- Speedplay's dual sided entry means you clip in without flipping the pedal, which on a technical start or in traffic is a real advantage.
- The adjustability Speedplay is known for, including independent float and stack adjustment, is preserved rather than compromised by the power hardware.
- An internal gyroscope removes cadence variation from the power calculation, which is the same technical approach the best pedal meters use.
Where it falls short
- Nearly a thousand dollars is the most expensive route to dual sided power, and the data is not better than Favero's at half the price.
- Speedplay cleats are more expensive and wear faster than SPD-SL, and they need the walkable covers to survive a cafe stop.
- The cleat and pedal system is polarising. Riders who love it will not change; riders who do not should buy a different meter.
- Like every pedal meter it is the part closest to the ground, and a crash can be expensive.
What owners report
Published owner reports come predominantly from existing Speedplay riders, who describe it as the product they had been waiting for. Power consistency reports are good and in line with the accuracy claim.
The criticism is price, and cleat wear, which is a Speedplay characteristic rather than a POWRLINK one. Reports comparing it with Favero and Garmin note that the choice is really about which cleat system you are committed to rather than about the power measurement itself.
Who it suits
- Riders already committed to Speedplay who want dual sided power.
- Cyclists who value dual sided entry and Speedplay's adjustability.
- Anyone using Wahoo head units who wants everything on one app.
Who should skip it
- Riders on any other cleat system, who have cheaper options.
- Anyone buying a first power meter on value, where Favero is the answer.
- Riders who walk a lot in cycling shoes, since Speedplay cleats are the least forgiving of that.
Alternatives worth considering
Dual sided power to the same claimed accuracy with rechargeable batteries, on the Look Keo platform. Unless Speedplay is non negotiable for you, this is the better value by a wide margin.

Is Speedplay worth staying with?
Riders who use it tend to be committed to it for the dual sided entry and the independent float and stack adjustment, which matters for knee issues and for precise fitting. Riders who have not used it rarely switch to it for the power meter alone. Buy this because you already ride Speedplay.
POWRLINK Zero or Favero Assioma?
The cleat platform decides it. The power data is comparable and Favero costs around half as much. If you ride Speedplay and will not change, POWRLINK. If you are open on cleats, Assioma is the value choice.
What is dual sided entry?
Both faces of a Speedplay pedal accept the cleat, so you never have to flip the pedal with your foot before clipping in. At a traffic light or a race start that is genuinely useful, and it is one of the main reasons Speedplay riders stay.
Does it work with non Wahoo head units?
Yes, it transmits standard ANT plus and Bluetooth power and cadence, so any modern head unit or watch will record it. Wahoo's own app and ELEMNT units offer the tightest integration for firmware and settings.
Is one percent accuracy meaningful in practice?
It is the standard claim across serious power meters, and consistency matters more than absolute accuracy for training. What genuinely matters is not mixing sources: use one device as your reference through a training block. Our FTP calculator works from whichever you choose.
