A power meter is the single, most effective training tool you can use for improving performance on the bike. You probably already know this. Well, this is perhaps especially true for track cycling. In the words of Andrew Coggan, Ph.D., co-author and cycling scientist behind Training and Racing with a Power Meter, “Given that on the track the difference between winning and losing is often extremely small, it can be argued that track cyclists may benefit from use of a power meter to an even greater extent than road (or off-road) cyclists.” However, track cycling is a smaller niche of cycling in general, so there aren’t a ton of choices when it comes to equipment for track cyclists. This includes track power meters.
The good news is, we have recently seen a few new track power meters hit the market. In addition, when you combine the track-specific options that do exist…with some road options that you can make work, you should be able to find something that will fit your needs. In this article, we explore what these options are. Let’s dive in!
Track Power Meters: Types and Options
Track power meters are just like any other power meter. Power sensors (aka strain gauges) are located within the power meter and measure the power, or torque, the rider generates. On a road bike, you can locate a power meter in about seven locations. These are: crank, pedal, bottom bracket, crank arm, hub or handlebar (OFPM). As previously mentioned, some of these options don’t exist for the track. But depending on your situation, the road version might work. Below, we have listed all of the power meter types and discuss what your options are for the track.
Manufacturer #1 – SRM
SRM makes perhaps the most popular and widely used track power meters, taking their ‘gold standard of power measurement’ to the track. SRM track power meters can measure up to 4,000 watts and are accurate to +/- 1.0%. The SRM Origin Track PM also features LOOK’s carbon crank arms and Trilobe Technology. Note the larger 144 BCD here. Standard road cranks are typically 110 (compact) or 130 BCD (standard). Track cyclists however run a larger size BCD and the SRM track power meter is manufactured to match.

Manufacturer #2 – power2max
power2max power meters are available as stand-alone spiders (that you pair to your existing crankset) or as complete cranksets. Their units are accurate to +/- 2.0% and feature dual-leg power measurement, left/right balance, Bluetooth SMART and auto-zero. For track, they offer the power2max NGeco ROTOR ALDHU Track Power Meter. If you already have a ROTOR ALDHU crankset, you can purchase the power2max power meter spider for $590. Otherwise, the power meter is available as a complete crankset for $790 (ROTOR ALDHU 24) or $890 (ROTOR ALDHU 30). Please note, the power2max ROTOR ALDHU Track Power Meter is only compatible with the ALDHU road axle.

Does the road option work – Not really
With a road crank, the largest BCD you could run is 130. This compares to the ideal track size of 144. In addition, road units typically have a 43.5 mm chainline. The optimal chainline for a track bike is 42 mm. (Note that you can attempt to address the chainline issue by moving the large chainring to the inner position.) If you are ok with these sacrifices, a crank-based road power meter is an option, but it’s not ideal.
2. Crank Arm
Manufacturer #1 – Verve Cycling
Verve Cycling, manufacturer of the Verve InfoCrank, makes a purpose built track version of the InfoCrank. The Verve InfoCrank Track Power Meter is accurate to +/- 0.5% and features independent left/right power measurement – the only track power meter capable of this. The InfoCrank Track Power Meter comes in a 144 BCD, is compatible with ISIS cartridge track bottom brackets and can measure up to 3,000 watts and 200 RPM. In addition, the power meter runs off of SR44 batteries and gets approximately 500 hours of battery life.

Manufacturer #2 – Stages Cycling
Stages Cycling manufacturers its Stages Shimano DURA-ACE Track Power Meter, which is built using a Shimano FC-7710 crank arm. The Stages track unit measures left-side power and sells for $649. Like other Stages power meters, it’s accurate to +/- 1.5%, gets 200 hours of battery life and only adds 20 grams of weight. In addition, it is both ANT+ and Bluetooth SMART compatible. If you have a compatible crankset and are trying to add power to your track bike without breaking the bank, it’s definitely a solid option.

Does the road option work – No
You can purchase a Stages, Pioneer or 4iiii road arm, however they will not be compatible assuming you are running a track crankset.
3. Handlebars (OFPM)
Velocomp’s PowerPod isn’t a track specific power meter, however since it simply mounts to the bars and uses opposing force technology to measure your power, it serves its purpose regardless of where it’s being used – track included. Note that conducting the initial calibration ride on the track can throw the unit off, unless you’re careful to ride around on the lower level surface only. Therefore, to be safe, we recommend performing the initial calibration ride somewhere other than the track.
Power meter pedals are perhaps the most popular power meter out (easy to install, dual-sided power, compatible with all bikes) – and you can indeed put one on a track bike. One consideration however is that some track cyclists like to use pedal straps. However, power meter pedals don’t lend themselves very well to these. If you do decide to use power meter pedals, we would recommend purchasing the optional 0 degree float cleats, as float is not your friend on the track.
5. Bottom Bracket
ROTOR makes its 2INpower and INpower DM power meters. These use strain gauges located in the bottom bracket and crank arm (2INpower). You can run these units on a track bike, however your BCD would be 110 and your chainline and Q factor not ideal. Please see our comments on the crank option.
So when you combine the dedicated track power meters that do exist, with road options that can be made to work on the track – you should be able to find something that works. Let us know if we can help. We want you to take advantage of the numerous benefits afforded by power data as you go around and around on the track! Until next time…!
