Power Meter Buying Guide – Review of the Best Models
Cycling power meters can help cyclists take their conditioning and speed to the next level. A good power meter might not be on the “basic needs” list for a beginner, but many intermediate and advanced cyclists and triathletes can benefit from one. Powermeters can be relatively easy to install, and used both with tri bikes and road bikes. For that matter, they can really be used with any bike, but most people who use them are trying to increase their training precision and crank up their speed. You wouldn’t lift weights without knowing how many pounds were on each dumb bell. The logic of power meters is the same — you can improve what you can measure. Most cyclists and bikers are gear junkies, but power meters add another level of sophistication to bike gear. They can be a bit difficult to get your head around because of the fundamentally different options available for measuring power, but we will try to simplify it in our guide below. First, we are going to get right to the point and share with you our favorite power meter models and setups for different situations. We are listing our favorite 4, from least expensive to most. Best Bike Powermeters For 2024 Best Pedal-Based Power Meter / Best Overall: Garmin Rally 200 Here. We hesitate to choose a single power meter model as best, because every type of power meter has its own merits and it can be hard to compare one to the other. We describe how various power meters work below, but if you want the simplest possible design this is it. Garmin makes a pedal-based power meter that measures our watt output based purely on the force exerted on the pedals. Yeah – that is pretty incredible. While you might miss just a bit of the accuracy of a full-on power-measuring system, we have found that pedal-based power meters give you everything you need on performance, and some pretty incredible data as well. It is a high-tech product and our experience is that the readouts are going to be accurate. We did a full Garmin Rally 200 pedal review. Note that Garmin suggests this power measurement is accurate for riders up to 240 lbs. Above that, we are not exactly sure what happens, but they suggest it might not work as well. An important factor to consider with the Rally 200 is the cleat type. This pedal is currently made in two pedal styles — the RS is the SDP-SL model, and the XC is the SPD model. You can get one-sided or dual-sided (meaning you can have just one pedal give you power readouts, or both). There is not reason to not go with the dual, other than the higher price. We had good luck with the batteries, good for up to 120 hours per the manufacturer and we believe it based on our field tests. As for getting your readout of power, the most common method is probably going to be to add the Garmin software to your phone and logging it that way. For those who want an easy way to monitor power while on a ride, you may want to mount the head-unit on your bike, but the place to track your data from ride-to-ride is on your Garmin Connect, not your watch or computer. The only issue we had was that the battery cover came off a couple times. We lost it once. You can save money going with the Rally 100 pedals, but that is only single-sided so you get none of the pedal symmetry stats. For $1,100, this is not cheap but if you have the budget, you will be astounded by the data provided. Of the choices you have, this is going to be by far the easiest and simplest to install. It is as easy as putting a new pedal on. Buy it direct from Garmin for the best deals and service. Runner-Up Power Meter: Stages Crank Arm-Based Powermeters Also at the simple entry level, but in a different concept, is the stages line of power meters. We love these. Like the Garmin, they rely on making just a slight adjustment on one side of your power system. Unlike the Garmin, the Stages model does it through a modified crank. The crank that you put on your bike is a carbon fiber, high-end crank that has a weight and material on par with the good Shimano and Campy products that come stock on your bike. They make models for mountain and road bikes – we are obviously focused more on road bikes (and triathlon bikes) in this review. The powermeter sits inside the left crank, and it is already fully installed and sealed inside. You don’t need to do anything but put the crank on the bike (with a torque wrench — these are delicate materials). The cons of a crank-based approach are that you are obviously messing with something — the crank length and design — that you might be completely comfortable with already. You really won’t feel much of a difference if you swap out hubs (noted below), but you may feel a difference when you use new cranks. Still, these are very well-designed cranks, so for most people it will be a lateral move or even an upgrade. The battery life is going to be significantly longer than the pedal model, at 200 hours or more. You can measure up to 2500 watts, which is more than enough for any cyclist on earth, same with the up-to 220 RPM tempo measurement. We love that the weight will only add about 18-20 grams to an otherwise 170-200 gram setup, hardly enough to even register. Note that it is designed to only go on one of your cranks (usually the left) so your reading will be from that side only. For most cyclists, that shouldn’t be an issue. The Stages Crank Arm-based meter comes in both Ultegra and Dura-Ace models, to … Read more
