Where to buy power meters USA

There are many, many options for power meters. The cheapest tend to be ones that simply replace the non-driveside arm of your current crankset. Alternatively, you can have the whole crankset replaced and benefit from the increased accuracy of having your left and right legs measured independently. 

Power meter pedals are generally more expensive than power meter cranks but on the other hand, they do provide you the option of easily swapping your power meter between bikes. 

Like with cranks, you can save a bit of money by buying a set of pedals where only the left side reads power. All the brands listed here provide the option to upgrade the right side pedal to a power meter version, should you want dual reading down the line

 Dual-sided power meter pedals

Garmin Rally RS200 Dual Sided SPD-SL Power Meter Pedals: $1,325.99

Garmin Rally RS200 Dual Sided SPD-SL Power Meter Pedals: $1,325.99 $1,012.49 at ProBikeKit Save $313.50 If you prefer the feel of Shimano's road cleats over anything else, you'll quickly find there aren't many power pedals on the market that cater for you. Fortunately, at least these from Garmin are on a hefty discount.

Garmin Rally RK200 Dual Sided Keo Power Meter Pedals: $1,325.99

Garmin Rally RK200 Dual Sided Keo Power Meter Pedals: $1,325.99 $1,012.49 at ProBikeKit Save $313.50 If your preference is for Keo style cleats, there's still that option in the Rally family. Something to note is that the pedal bodies are all interchangeable, so should you wish to change to Shimano road or Shimano MTB cleats down the line, you won't have to buy a whole new set of pedals 

Garmin Rally XC200 Dual Sided SPD-SL Power Meter Pedals: $1,449.49

Garmin Rally XC200 Dual Sided SPD-SL Power Meter Pedals: $1,449.49 $1,188.49 at ProBikeKit Save $261.00 If you're after power readings off-road – whether on a gravel or mountain bike – you'll quickly find there aren't as many options as there are for road. Even fewer if you've got a preference for pedals.

Garmin Vector 3 Double Sided Power Meter Pedals: $1,079.99

Garmin Vector 3 Double Sided Power Meter Pedals: $1,079.99 $666.49 at ProBikeKit Save $413.50 Being the previous generation of Garmin's power meter pedals, the Vector 3 doesn't let you swap out the pedal body as you can with the Rallys.

But if you're happy just sticking with Keo style cleats, you can take a massive saving over the latest model. Although the Vector 3 pedals were beset with accuracy issues when they first launched, these have since been solved and the Vectors offer the same +/-1% claimed accuracy as the Rallys

 Single-sided power meter pedals

Garmin Rally RS100 Dual Sided SPD-SL Power Meter Pedals: $792.99

Garmin Rally RS100 Dual Sided SPD-SL Power Meter Pedals: $792.99 $620.99 at ProBikeKit Save $172.00 Just the same as the dual-sided option in offering a great option for getting power meter readings while keeping your Shimano road cleats – but with only the left pedal providing the power readings.

Garmin Rally RK100 Dual Sided Keo Power Meter Pedals: $792.99

Garmin Rally RK100 Dual Sided Keo Power Meter Pedals: $792.99 $605.99 at ProBikeKit Save $187.50 Likewise, the single-sided Keo style cleat version provides a cheaper entry into riding with power. As with all the Rally pedals, the bodies are interchangeable so, should you wish, you can always upgrade the pedals to suit a different style of cleat.

Garmin Rally XC100 Dual Sided SPD-SL Power Meter Pedals: $847.99

Garmin Rally XC100 Dual Sided SPD-SL Power Meter Pedals: $847.99 $656.00 at ProBikeKit Save: $191.99 Again, a cheaper way to combine power meter readings with the ease of clipping in and out that comes from the SPD system.

Garmin Vector 3s Single-Sided Power Meter Pedals: $682.49

Garmin Vector 3s Single-Sided Power Meter Pedals: $682.49 $509.00 at ProBikeKit Save $173.49 Just like its dual-sided sibling, going for the previous generation of Vector 3 power meter pedals can save you masses over the latest Rally pedals. The only downside being that you don't get the switching pedal body functionality – but if you're happy with Keo, there's little reason to pay extra for that capability. 

 Power meter cranksets

FSA Alloy PowerBox Power Meter Crankset: $735.00

FSA Alloy PowerBox Power Meter Crankset: $735.00 $588.00 at Backcountry Save $147 If you're after dual sided readings on just one bike, a power meter crankset can be the most cost effective option – especially if you're thinking of changing your crank length or chainring sizes at the same time. 

Just bear in mind that the PowerBox's spindle is 30mm, so if you're currently running Shimano cranks you'll need to factor in the cost of a new bottom bracket. Also, so access the dual sided functionality, you'll need to pay FSA a surcharge, otherwise it'll just give single sided readings.

4iiii Precision Pro Dual Sided Power Meter $791.99

4iiii Precision Pro Dual Sided Power Meter $791.99 $550.99 at ProBikeKit Save $241.00 If you're after dual-sided readings and for cheaper than a set of power meter pedals, then you've hit the right deal. With a 24mm spindle, it'll be a straight swap for most Shimano road cranksets. You could also take the opportunity to experiment with different gearing sizes and crank arm lengths.

SRAM Rival AXS Power Meter Chainset $440.49

SRAM Rival AXS Power Meter Chainset $440.49 $344.99 at ProBikeKit Save $95.50 Again, a little bit of creative licence with this one. While it is a crankset and it is on offer, SRAM's Rival AXS Power Meter will only take readings from your left leg and there is no optional upgrade.

But in coming with chainrings and both crankarms, we felt it was more at home here than with the left side only power cranks. It also represents a pretty low barrier to entry for adding power to your rides on a SRAM AXS equipped bike.

 Single-sided power cranks

4iiii Precision 105 R7000 Powermeter: $389.90

4iiii Precision 105 R7000 Powermeter: $389.90 $286.00 at Wiggle Save $103.90 One of the cheapest and simplest ways of adding power readings to your bikes. The cost is so low compared to a set of power meter pedals, you could buy two of these cranks and save on continually swapping pedals – as well as a bit of money. 

4iiii Precision Ultegra R8000 Powermeter: $455.10 $330.00 At Wiggle Save $125.10 Alternatively, if you're currently running Ultegra and want to keep everything matchy-matchy, those cranks are currently on a discount too.

Avio Powersense Power Meter: $272.49

Avio Powersense Power Meter: $272.49 $158.49 at ProBikeKit Save $114.00 For an even cheaper way of adding power to your rides, Avio enables you to fit the strain gauge yourself, saving the cost – and waste – of buying a whole new crank arm. Bear in mind that you'll also need to purchase the fitting kit separately, which costs around $40

4iiii Precision 2.0 Shimano GRX power meter: $477.49

4iiii Precision 2.0 Shimano GRX power meter: $477.49 $331.99 at ProBikeKit Save $145.50 If you're looking for power readings on your gravel bike, the most affordable method is through a left hand power crank, rather than any dual reading cranksets or left side SPD power pedals. 

4iiii Precision 2.0 Shimano GRX power meter: $477.49

4iiii Precision 2.0 Shimano GRX power meter: $477.49 $331.99 at ProBikeKit Save $145.50 If you're looking for power readings on your gravel bike, the most affordable method is through a left hand power crank, rather than any dual reading cranksets or left side SPD power pedals.
