Power Meters Compared

A decade ago the choices of cycling power meters were limited and expensive, restricted to professionals and well-off amateurs. Nowadays though, we are completely spoilt for choice, and there are dozens of brands available at a variety of price points.

The important thing to remember is that accurate, reliable power measurement is quite difficult, and the more expensive manufacturers will typically have spent much longer than others on the research & development cycle. Therefore you will pay more for a meter that is tested more thoroughly over more of the power spectrum, so should expect it to last longer and be more consistent with readings. Newer, cheaper entries to the power meter market may or may not have come up with a product that will last as long or as well - so buyer beware!

LIMITS Power

Reliability
Accuracy
Value
Compatibility

A crowdfunded power meter that is intended to be as interchangable and easy to install as possible, by sitting between the left pedal and left crank arm. It certainly is easy to swap around (as long as you have the couple of special tools to hand) but calibration is tricky - it's very sensitive to the crank position, and recorded power can start drifting mid-ride.

SRM Exakt Power Pedals

Accuracy
Value
Compatibility

£1,280 from 1 retailer

The first non-crankset power meter from SRM, this one sits inside a pedal spindle manufactured by Look. Careful design and integration mean that the pedal's profile is pretty much the same as that of a regular high-end pedal, and it is only slightly heavier too. Recharging is performed using a hex-shaped adapter that plugs into the crank end of the pedal spindle, allowing for simple USB charging. It's jus as well that recharing is easy, as each pedal apparently only lasts around 90 hours of use.

Powertap G3 hub

Reliability
Value
Compatibility

£74 - £631 from 5 retailers

This is a long-time favourite of power meter enthusiasts, as the measurement is done in the rear wheel - mostly out of harm's way, and with plenty of room to do the measuring. Powertap sells the hub only, allowing you to build your choice of wheel. The wheel is obviously transferable between bikes, which is good. The "true" combined power of both legs is captured, but you won't be seeing any left-right balance data.

IQ2

Value
Compatibility

This is an adaptor that sits between the pedals and the crank, so can be used on any bike. It is quite a slim unit, but still increases the "Q factor" by 16mm per pedal. Left and right versions will be available, and you can choose whether to have just one or to have both.

Powermax only sells direct, and offers a range of spiders (including cranks if required) to suit various cranksets.

STYX Powermeter

Compatibility

Power meter is embedded in each cleat (either Shimano SPD-SL or Look Keo), and will therefore work on any bike with the matching pedals fitted. This is a crowd-funding campaign, and there is a risk that the product may not be delivered as anticipated.
