The entire SportOptim team thanks you for choosing our CyclOptim pedals to track your performance! By choosing our products, you're supporting a young Bordeaux-based company committed to working with local partners — not only for environmental reasons (cutting unnecessary logistics miles) but also to promote French industrial expertise.

This manual provides everything you need to get the most out of your CyclOptim experience! We chose to offer a digital manual so it can be easily updated and enriched with your questions and feedback as needed.

Welcome to the front of the peloton — enjoy your power meters, push your performance, and most importantly, have fun riding!

Before fitting and using your CyclOptim pedals, please read this user manual carefully, along with the safety and maintenance instructions. Improper use or installation could lead to accidents or damage your pedals.

If you're new to cycling, don't hesitate to contact your local bike mechanic or bike shop for help with the installation. Damage resulting from improper installation is not covered by the warranty.

To install / remove your pedals you will need:

• A 15mm flat spanner
• A 2.5mm Allen key
  

Warning: SportOptim does not supply cleats with its products, but offers KEO®, SPD-SL®, and SPD® cleats for purchase. To avoid damage or injury, only use cleats sold by SportOptim or genuine cleats from these brands. SportOptim cannot be held liable for any damage or injury resulting from the use of cleats not intended for CyclOptim pedals.

CyclOptim pedals are not designed for use with flat shoes. Always use cycling shoes fitted with the appropriate cleats to avoid damage to the platforms or the sensor.

If you purchased cleats from our website along with your CyclOptim pedals, you will find them in a small kraft envelope, complete with their mounting screws.

💡 Tip: If you are replacing your existing cleats with ours, take a moment to trace around your current cleats onto the sole of your shoes with a marker or pencil. This will let you position your new cleats in exactly the same spot without having to readjust from scratch.
Remove your current cleats, check the sole is clean, then fit the new cleats in the marked position.

Place the cleat, then fit the backing plates and screws. Tighten carefully, making sure the cleat doesn't move during the process. We recommend a torque of 4–6 Nm.

Before heading out, check that the cleat position feels right and adjust if needed. Loosen the screws, reposition, and tighten back up.

• Step 1: Clean the pedal tightening thread on your bike crank.
• Step 2: Insert the first pedal's axle into the crank. It's important to be able to screw the pedal in completely by hand, and only use the wrench for final tightening.

Note: The axles are pre-greased, so there's no need to add grease during the initial installation. If you remove your pedals to transfer them to another bike or for storage, we recommend light greasing before the next installation.

• Step 3: Tighten the axle using a 15mm open-end wrench. When facing your pedal, the tightening motion is counter-clockwise for the left pedal and clockwise for the right pedal.
  We recommend a tightening torque between 35 and 40 Nm. However, if your crank manufacturer recommends a lower tightening torque, use their recommended values.

Warning: If your crank tightening thread is recessed compared to the crank body, it is necessary to use the washers provided to avoid any friction damage to your cranks.

• Step 4: Repeat for the second pedal.
• Step 5: Once both pedals are installed, turn the cranks through a full rotation to check for any obstruction.

Your pedals are now installed and set up. It's time to sync your GPS computer or smartwatch with your sensors.

NB: The current firmware on your CyclOptim pedals only uses the ANT+ protocol. You can therefore synchronise your sensors with any compatible GPS cycling computer or smartwatch that supports this protocol. A list of compatible devices is available here.

As the pairing process varies by manufacturer, we recommend consulting the manual for your GPS cycling computer or smartwatch. A few tips for a smooth pairing:

• Make sure your GPS computer or smartwatch is within 2 metres of your pedals.
• Make sure you are not surrounded by too many other sensors. If needed, move at least ten metres away from teammates or competitors before pairing.
• Make sure your sensors are charged and turn the cranks a few times to wake them from sleep mode.
• From your GPS computer or smartwatch, run a scan to search for and pair a new accessory.
• The ID code for your CyclOptim pedals corresponds to the last 4 digits of the serial number on your left spindle.
• Your device will confirm that your sensors have been successfully paired.

NB: Communication between your GPS computer or smartwatch and your pedals occurs via the left pedal only, regardless of the model you are using (Lite or Classic).

Once paired, a few configuration steps are required to ensure your sensor data is accurate and reliable. This configuration is essential for consistent power measurement.
You will need to repeat these steps each time you switch bikes. We also recommend performing a manual zero-offset regularly — even if your pedals have not been removed — to ensure data consistency.

Once calibration is complete, your GPS computer or smartwatch will return a confirmation value if successful. This number represents the offset value of your left spindle relative to the crank arm. If you repeat the calibration multiple times on the same bike without removing and reinstalling your pedals, this value should remain consistent.
If the calibration was unsuccessful, your device may return an error code. Refer to the table below to complete the calibration successfully.

Your CyclOptim pedals have a battery life of approximately 25 hours. There is no need to remove your pedals for charging, as the connector is accessible from the back of the crank. To charge your sensors, use the provided cables, which you can connect via USB to your computer, car, or power bank. You can also use your phone's mains adapter.

Note: If your phone uses a fast charger, you can use it safely — charging will not be faster than with a standard charger, as fast charging is not supported by your sensors' batteries.

Your chargers use a magnetic connection. Depending on how clean your pedals and charger are, the magnet may not hold as strongly. Poor magnetic contact can reduce charging efficiency if the cable shifts out of alignment — that is, with the connectors no longer facing each other properly. To avoid any issues, feel free to use parts of your bike to support the cable weight (bottle cage, drivetrain, spokes, etc.) and keep the connection secure throughout charging.

Before engaging in a sport or starting a new training programme, consult your doctor to assess your health.

CyclOptim pedals are not a medical device; whilst power is a useful metric for tracking your fitness, our sensors are not intended for healthcare purposes.

For your safety and the safety of all road users, always ensure you comply with the Highway Code and carry the required equipment when cycling on public roads.

As with any electronic device fitted with a lithium-ion battery, do not expose your pedals to intense heat (e.g., a car parked in direct sunlight in summer), and keep them away from fire and explosive environments. Batteries must not be dismantled, replaced, modified, or punctured under any circumstances.

Please note that CyclOptim pedals contain small parts that may be swallowed by children. If ingestion is suspected, contact a doctor or emergency services immediately.

Your pedals are recyclable — remember to drop them off at a dedicated recycling point so the electronics can be properly processed and recovered. Plastic components can go in your regular plastic recycling bin.
