Additional All Road Power Meters Info:

All these road bike power meters are accurate to within 1.0 – 2.0%. Some measure left leg power while others measure both legs. On every power meter’s product page, you can find this information and much more. Here is a quick overview of each brand’s road power meters:

4iiii

4iiii makes crank arm power meters for Shimano cranksets. They currently offer left-side crank arms for Shimano 105 R7000, Ultegra R8000 and DURA-ACE 9100. They also offered dual-sided cranksets for these same models. These power meters feature a 3-year warranty.

Favero

Favero sells the popular Assioma power meter pedal. The DUO measures both legs and the UNO measures left leg power. They use LOOK Keo style cleats. We also have the Favero Assioma DUO-Shi which is a power meter spindle that is compatible with select Shimano pedal bodies, allowing you to use a Shimano SPD-SL cleat.

Garmin

Garmin makes power meter pedals. For road, they have the Rally RS pedal that uses Shimano SPD cleats, as well as the Rally RK that uses LOOK Keo cleats. Both power meter pedals are offered in a dual-sided version (RS200 and RK200), as well as a single-sided version (RS100 and RK100). One very unique thing about the Garmin pedals is you can buy a pedal body conversion kit that allows you to use the same power meter with different cleats (road and MTB, for example).

LOOK

LOOK, in combination with SRM, makes the EXAKT power meter pedal. This pedal is a bit on the pricey side compared to other road pedals, however we like that it has fully integrated design and so it looks like a normal pedal.

power2max

power2max makes power meter spiders. These power meters bolt to your crank arm and you then attach a chainring to the power meter. They measure power from both legs, are accurate and reliable. They offer road power meter spiders for SRAM, Praxis, ROTOR, Specialized, Easton, Cannondale and Campagnolo cranksets. These are great power meters, affordably priced and work very well.

ROTOR

ROTOR makes crankset power meters. This means you replace your existing crankset with the new power equipped version. For road, they have the 2INpower Road Power meter and the INpower Road Power Meter. The main difference is the 2INpower measures power from both legs, whereas the INpower measures left leg power only. These are great, solid units, however the 2INpower is a bit on the pricey side. They also offer the INspider which is a spider-based power meter that bolts to ROTOR ALDHU and VEGAST crank arms.

Shimano

Shimano makes power meter versions of their own cranksets. We currently have dual-sided cranksets for Ultegra 8100 and DURA-ACE 9200. These road power meters feature dual-leg power measurement, left vs. right leg power, 300+ hours of battery life and use a rechargeable battery. They are hard to get and we sell them about as fast as we can get them in stock!

SRAM and Quarq

SRAM and Quarq make a range of power meters for road bikes. Most of their power meters are spider-based and are compatible with SRAM RED, SRAM Force or Quarq DZero cranks. The RED AXS power meter, available in both 2x and 1x versions, is their flagship crankset featuring integrated chainrings. They also have the DZero (fits 5-bolt rings) as well as the DFour (fits 4-bolt Shimano chainrings).

SRM

SRM makes crankset power meters. They offer the Origin Road Power meter which measures power from both legs. One thing that is nice about the SRM is they are highly configurable. You can order it with different crank arms (several versions of carbon as well as aluminum) and different spindle sizes. They also offer a version that uses Campagnolo crank arms. SRM power meters are the most expensive options, however the company enjoys a solid reputation, as they have the most experience of any power meter manufacturer.

Stages

Stages makes crank arm power meters, however unlike 4iiii, they offer road power meter crank arms for a range of road cranksets. This includes power meters for Shimano, FSA, SRAM, Easton, Specialized, Cannondale and Campagnolo cranksets. They also offer entire cranksets for Shimano Ultegra R8000 and DURA-ACE 9100.

Velocomp

Velocomp makes handlebar-mounted power meters. These don’t have the accuracy of a direct force power meter (like the other ones on this page). However, they are affordable, can be used on any bike and can be moved between bikes, which are some big advantages most other power meters can’t claim.

Wahoo

Wahoo makes the POWRLINK ZERO, which is the only Speedplay compatible power meter pedal. It’s available in both dual- and single-sided versions and offer a quick and easy way for Speedplay users to add power to their road bike.
