SRM X-Power SINGLE MTB Flat Pedals

The SRM X-Power Single Flat is a single-sided pedal power meter. The power is measured on the right pedal. The left pedal is supplied without measurement electronics. Especially for the all-mountain / MTB and trekking field there were long no powermeter pedals without a clipless system. SRM has closed this gap with the X-Power Flat pedals.

The SRM X-Power Single Flat pedals have a rechargeable battery and offer a measurement accuracy of ± 2%. The pedals are manufactured by SRM in Jülich near Cologne in Germany.

Single-sided measurement

In the SRM X-Power Flat Single only the right pedal is equipped with measurement electronics. The power is doubled to estimate the total power. For many riders, this may be enough. It becomes problematic when one leg is stronger than the other. Then the total power inevitably deviates. Moreover, such a dysbalance is rarely constant, but shifts depending on muscular fatigue and the level of power output.
The SRM X-Power Flat Single are therefore suitable primarily for beginners and riders with a tight budget, who can do without the last percent accuracy. Ambitious riders who want to know exactly and want to learn more about their pedaling technique are better served with the double-sided SRM X-Power Flat Dual.

Compatible bike computers and smartphones

ANT+ capable bike computers (Garmin, Wahoo, O-Synce, Sigma, SRM, etc.) work without problems with the SRM X-Power Flat. Since the data transmission of the SRM X-Power Flat also takes place via Bluetooth Smart, the powermeter can also be paired with smartphones.

Compatible bikes

The SRM X-Power Flat 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 Flat pedals. Also other cyclists who want to ride without a clipless pedal but not a powermeter, will love the X-Power Flat 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 Flat pedals very robust and durable.

Weight

The pedal set weighs in at 410g including measurement electronics and battery. Thus, the SRM X-Power Flat pedals are in an average range for flat pedals without a built-in power meter!

Accuracy

An accurate measurement is not so easy with flat pedals, because the foot is not fixed on the pedal as with a clipless pedal and therefore often takes a slightly different position on the pedal. Nevertheless, SRM has managed to achieve a measurement accuracy of +-2%.

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 Flat 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 Flat 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

At product launch, the SRM X-Power Flat pedals had a few teething issues and there were problems at SRM with some suppliers. Meanwhile, the problems have been solved and the X-Power Flat pedals are now reliable and robust.

Warranty and support

The SRM X-Power Flat 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.
