Why choose Powermetershop?
- Order number: SW10798
The SRM X-Power DUAL is a double-sided pedal power meter. The left and right leg are measured completely separately from each other. The SRM X-Power is compatible with the Shimano SPD system.
The SRM X-Power DUAL pedals have a rechargeable battery and offer a measurement accuracy of ± 2%. The pedals are manufactured by SRM in Jülich near Cologne in Germany.
Highlights and Downsides
- dual-sided power measurement with a ± 2% accuracy
- rechargeable battery (30h operating time)
- integrated cadence measurement
- Shimano SPD compatible
- low weight (388g for both pedals)
- automatic temperature compensation
- easy to swap between bikes
- works with many bike computers and smartphones (ANT+ & Bluetooth)
- only compatible with shoes with 2-hole standard
- in a crash, the bike usually lands on the pedal
Dual-sided measurement
In the SRM X-Power DUAL both pedals are equipped with measurement electronics. This allows power and force distribution to be measured individually for each leg. Especially in case of muscular imbalances, you are at an advantage with the double-sided SRM X-Power. This makes the DUAL particularly suitable for ambitious riders who want to know exactly and want to learn more about their pedaling technique.
For beginners and riders with a tight budget who can do without the last percent accuracy, the single-sided SRM X-Power Single is a good alternative.
Compatible bike computers and smartphones
ANT+ capable bike computers (Garmin, Wahoo, O-Synce, Sigma, SRM, etc.) work without problems with the SRM X-Power . Since the data transmission of the SRM X-Power also takes place via Bluetooth Smart, the powermeter can also be paired with smartphones.
Compatible bikes
The SRM X-Power pedals can be used with any bike. Especially for the all-mountain and trekking field there were long no power meter pedals without a clipless system. SRM has closed this gap with the X-Power pedals. Also other cyclists who want to ride without a clipless pedal but not a powermeter, will love the X-Power pedals.
Rechargeable battery
The batteries have an operating time of 30 hours and are rechargeable via a magnetic plug. This means that there is no opening in the housing of the electronics and the pedals have no battery cover (no wear, no water entry).
Construction and design
The complete electronics including battery is installed in the pedal axle and thus protected from external influences such as moisture and dirt. There is no opening in the housing of the electronics and the pedals have no battery cover (no wear, no water entry). The pedal body is made of anodized aluminum. The pedal axle is made of steel. This construction makes the X-Power pedals very robust and durable.
Weight
The pedal set weighs in at 388g including measurement electronics and battery. Thus, the SRM X-Power pedals are in an average range for pedals without a built-in power meter!
Accuracy
We were able to confirm SRM's stated measurement accuracy of ± 2% on our calibrated Cyclus II ergometer.
Setup and firmware updates
Screw the pedals to the crank arms with a normal 15mm pedal-wrench. Then launch the X-Power app (iOS and Android). After the app has found the pedals (rotate pedals to wake them up from standyby), go to "Installation" in the app and follow the steps. The app will guide you through the setup: Set crank arm length, zero calibration and alignment. And you're done! Firmware updates are also installed via the app.
Installation
The installation is very simple - the SRM X-Power pedals are simply screwed to the bike like normal pedals. A real plug 'n play powermeter. This also allows easy switching between different bikes. In addition, the SRM X-Power pedals can also easily be taken on vacation or to the training camp and mounted there on a rental bike. Since the electronics are built into the pedal axle, the assembly is not possible with an Allen key. A 15mm standard pedal wrench is required.
Durability
There is no opening in the housing of the electronics and the pedals have no battery cover (no wear, no entry of water). The pedal body is made of anodized aluminum. The pedal axle is made of steel. At the product launch, the SRM X-Power pedals had a few teething problems and there were problems at SRM with some suppliers. Meanwhile, the problems have been solved and the X-Power pedals are reliable and robust power meter pedals.
Warranty and support
The SRM X-Power pedals come with 2 years warranty. The pedals are produced by SRM in Germany. The German support is very good and customer-oriented. If there is ever a problem, we have a direct line to SRM and can help you quickly.
Optional: PC8 Bundle
The optional PC8 Bundle is the perfect complement for the SRM Power Meter. You get the SRM Powercontrol 8 bike computer with speed and HR-sensor for an attractive price.
The PC8 is a minimalistic bike computer. The functions are tailored to the needs of athletes. It therefore is very popular and frequently encountered in the pro peloton.
The PC8 has a GPS function that can be used to record training or competition. The GPS function can be turned off, as can the backlight - increasing battery life to up to 45 hours.
Thanks to the generous memory of 500MB, approximately 4000 hours of training and competition can be recorded in the user-friendly .fit format. The built-in motion sensor automatically activates the PC8 as soon as the ride is started.
Up to four different bike profiles can be created, eliminating the hassle of pairing with different power meters on different bikes. The display is freely configurable.
Included in the bundle are heart rate belt and speed sensor.

Worth waiting for.
I've had to wait a while to get these but nowhere near as long as some are waiting for competitor's models. Having waited, I'm more than pleased.
Setup, charging, moving between bikes and connecting is quick and straightforward. Readings all look good to me.
They look and seem rugged and having had SPD pedals on all my VTT, road and indoor bikes they are what I've been wishing for over the past few decades.
I would quite like some plain pedal bodies without logos so people can't see my €400 bike has €1100 pedals on it.
