Stages really exploded this category with their left-only power meter, and other vendors followed suit including Garmin (Vector S), Rotor (Rotor LT, ROTOR in POWER), 4iiii (some models), LIMITS, and Polar (Keo Power Essential).
Note that all bottom-bracket power meters are left-only power. Estimated Left/Right Power: This became all the rage just prior to true left/right units coming out, starting with the SRAM/Quarq RED unit offering left/right power. Note that even with true left/right power (below), there’s actually very little in the scientific community around what to do with the data.
If there’s anything I want to change in the industry it’s the mindset that there is a single perfect power meter for every consumer.
Thus, if you ask someone for “the best power meter”, and they give you any answer “it depends”, don’t trust that person.
For example, it’d be silly to go out and buy Garmin Vector if you’re looking to put it on a mountain bike.
Also note, for companies where they OEM a secondary product, I’m just focusing on the primary name-brand product.
For example, Cateye is simply 4iiii, and FSA is simply Power2Max re-branded.
Now that we’ve covered where each unit goes, let’s talk about the features that the power meters on the market have today: Total Power (Watts): This is the obvious one – every power meter has this today (even estimated ones! This is simply measuring and transmitting your total power output to a head unit of some type.
Note that I’m not going to cover why you’d use a power meter here, nor how to use it. Instead, I’m just going to focus on the products out in the market today, and those coming down the road.
Finally, remember that power meters tend to be about as fiery as politics and religion. There are certainly other views out there (all wrong of course), but this comes from my perspective of trying out all the products below and hearing feedback from literally hundreds of people per day.
