More Details On Our Top Picks
Road riders already running SRAM DUB components get a clean way to add power data without changing pedals. This left crank arm measures left-side output and doubles it for total wattage, a common single-sided approach that keeps the setup light. You need a matching right arm, spider, chainring, and bottom bracket, since those parts ship separately.
The 165mm length and 47.5mm chainline suit a precise fit check before ordering. Carbon construction keeps weight down for performance road riding, and IPX7 protection covers wet conditions up to 1 meter for 30 minutes. ANT+ and Bluetooth LE let a compatible computer or app receive the data.
What Stands Out
- Carbon left arm keeps the crankset light for road use
- ANT+ and Bluetooth LE cover most computers and apps
- IPX7 protection suits rainy training rides
- 165mm length matches a common road fit
Things To Consider
- Right arm and drivetrain parts ship separately
- Single-sided measurement cannot show left and right balance
Unlike the SRAM crank arm, this pedal system moves between bikes in minutes and needs no crank compatibility check. Each pedal weighs 130g, with a carbon-fiber-reinforced techno-polymer body and needle roller bearings. Look Keo cleats in 5 degrees are included for riders already using that system.
Power accuracy is listed at plus or minus 1 percent using the IAV system, which tracks angular velocity for metrics such as cadence, power phase, and pedal smoothness. Your rechargeable battery runs up to 160 hours per charge, and auto-calibration removes manual setup. Three simultaneous Bluetooth connections plus ANT+ cover a computer, watch, and app at once.
Where It Excels
- 130g per pedal keeps road weight low
- 160-hour battery reduces charging frequency
- Auto-calibration simplifies setup between bikes
- Advanced metrics help analyze pedaling technique
- Modular bodies allow road and MTB swaps
Worth Noting
- Look Keo cleat compatibility limits pedal choice
Who It Suits Best
Road riders using Look Keo cleats who want pedal power without crank changes.
Where Another Pick Suits Better
Favero Assioma Pro RS-2 suits riders who want left and right balance data instead.
Dual-sided measurement sets this apart from the RL-1, since each pedal reports its own output. Left and right balance, torque effectiveness, and pedal smoothness come from the IAV system with plus or minus 1 percent accuracy. You get that detail even with oval chainrings, which some single-sided setups handle less cleanly.
At 123.5g per side, the carbon-fiber tech-polymer body stays light for road training. A rechargeable lithium-ion battery provides over 60 hours per charge, shorter than the RL-1 but paired with true dual-sided data. Electronics sit sealed in the spindle, and pedal bodies can be swapped for road or MTB use.
Good Reasons To Consider
- Dual-sided data shows left and right balance
- 123.5g per side keeps road weight low
- Sealed spindle design simplifies body replacement
- SPD-SL cleat compatibility covers SM-SH10, SH11, and SH12
Trade Offs
- Battery life is shorter than the RL-1 at over 60 hours
- Dual-sided pedals cost more than single-sided options
- SPD-SL cleat system must match current shoes
Gravel and MTB riders get a different build from the road-focused RS-2. The MX-2 uses an aluminum 6061-T6 pedal body for rough terrain, with a clipless surface hardness up to 800 HV. That construction suits rocky trails where a carbon road pedal would feel out of place.
Your electronics and rechargeable battery sit inside a compact spindle, and magnetic charging avoids cable tugging issues. One charge provides at least 60 hours of use. Bluetooth and ANT+ connect with most bike computers, watches, and training apps, and installation takes minutes without special tools.
The Upside
- Aluminum body suits gravel and trail use
- Magnetic charging simplifies cable management
- Swaps between bikes like standard pedals
Minor Gripes
- Trail build adds weight compared with road pedals
- SPD cleat system must match current shoes
Made For
Gravel and MTB riders who want dual-sided power on rough terrain.
Consider Something Else When
Favero Assioma Pro RS-2 suits road riders who prioritize low pedal weight.

What To Check Before Adding ANT+ Gear
Match The Sensor To The Bike
Crank arms need exact length, chainline, and spindle compatibility. Pedal systems need cleat alignment with current shoes. A mismatch here blocks installation, so confirm those details before ordering.
Decide What Data Matters Most
Single-sided power keeps cost and weight down. Dual-sided power adds balance data for technique work. Computers add route guidance, sensor display, and training structure, depending on screen type.
Check Battery And Charging Habits
Long battery life suits riders who charge weekly. Magnetic charging reduces cable wear on pedals. USB-C charging speeds turnaround on computers. Match charging style to a realistic routine at home.
Confirm Computer Compatibility
ANT+ and Bluetooth LE cover most modern computers and apps. Older head units may lack Bluetooth, so check supported protocols first. Multi-device support matters for riders using a watch, computer, and phone together.
Key Considerations Across These Picks
Common Shopping Slip Ups
Ordering a crank arm without measuring length causes return hassle. Ignoring cleat type leads to shoe changes. Checking those two details first saves time.
What The Higher Tier Buys
Dual-sided pedals add balance metrics that single-sided systems cannot show. Larger color screens add route guidance and custom layouts. Paying more makes sense for structured training and exploration.
Frequently Asked Questions
What does ANT+ do on a cycling power meter?
ANT+ sends power, cadence, and other sensor data wirelessly to a computer or app. That link lets training data appear on a head unit during a ride.
Are pedal power meters easier to move between bikes?
Pedal systems swap like standard pedals and need no crank compatibility check. Crank arms require matching spindle, length, and chainline.
What is the difference between single-sided and dual-sided power?
Single-sided systems measure one leg and double the value for total power. Dual-sided systems measure each leg and show balance between sides.
Can a GPS computer display power data from a sensor?
Yes, computers with ANT+ or Bluetooth can receive power from compatible sensors. Screen size and data field layout affect how clearly those numbers read.
What should be checked before ordering a crank power meter?
Crank length, chainline, spindle interface, and drivetrain speed count must match the bike. Missing any one detail can prevent proper installation.
Final Verdict
Road riders focused on training data get strong pedal options in the Favero range, while SRAM suits DUB crank setups. GPS computers cover display and route needs at different levels. Match the sensor type to the bike first, then let data needs guide the final choice.
