It may seem strange to think that today powermeters have drawbacks, right? At the end of the day, it is a technology that we have fully incorporated into our bikes and for many of you it is something already considered an essential. In addition, integrated systems such as the 2INpower from ROTOR have made it easier to use and install. If you are not convinced about using a powermeter, we give you the keys to clarify your ideas.

What a few years ago was considered a territory almost exclusively for professionals, today is an alternative that is available in a multitude of options, such as the INpower from ROTOR, so you can measure as accurately as possible everything that is happening when you pedal on your bike. Powermeters are an ideal tool that allows you to obtain among other things, the total amount of watts that you apply in each pedal stroke, the percentage of force and watts from one leg or another, the cadence of pedaling, the force applied during the complete pedal cycle and of course all the values associated with an original speedometer depending on the model. But if you are not convinced whether or not to buy one of them, here at ROTOR we want to help you by explaining the advantages and disadvantages of using a powermeter.


Training planning

Planning the season with the help of the powermeter is much easier. The accumulation of data and its comparison, as well as its use of percentages, can help us plan a calendar with clear objectives. The watts generated by pedaling are a very precise and objective indication of the power we are generating at each moment. We can know our pre-season maximum with which to compare our development throughout the months of training. It will also help us to measure the cadence and if we want to work to vary it, we will have all the training data to be able to compare. In addition, if you are a user of the ROTOR 2INpower, you can compare the data between one leg and another, in addition to controlling the complete 360-degree pedal cycle, to assess the power you apply at each moment of it.


If you come from using heart rate based training in recent years, the jump to the level of reliability if you start training with a potentiometer is huge. The accuracy in the measurement of the heart rate can be affected by many values, such as heat, tension, stress, time of the day … This means that, although cardiac control is something to take into account in training, especially to monitor possible periods of over training, a powermeter is much more accurate as it tells us the real power we are applying to the pedals at all times.

Training zone control

Intensity zone training, based on the powermeter measurements is much more effective since you can calculate the real maximum power output, or the maximum number of watts you can generate, so, from that 100% maximum intensity, you can set the intensity zones you want to choose in each phase of the training. This allows us to quantify the performance in a more real and objective way than we could obtain by only measuring the heart rate.

In addition, the control of the training by watts also allows us to convert that spent energy, those watts applied whilst pedaling, to calculate the caloric expenditure during training and competitions. This will help us when planning training diets, and having an adequate caloric intake controlled depending on our effort.

Independent data for each leg

Powermeter such as the ROTOR 2INpower or INspider as well as some models from other manufacturers, allow us to measure in real time, the intensity and watts of power generated by both legs in an independent way. This is something very useful in regards to the ergonomics of the bike and biomechanics, in order to find the most effective position on the bike and achieve a total balance between both legs when applying force to the pedals.

Variety of models

Over the years, what was once an almost exclusive territory for professionals, is now open to everyone. The variety and prices of powemeters that are currently on the market, make it easier and easier to access them regardless of the type of bottom bracket and cranks we use.


Difficulty reading data

Current powermeters offer so much data that they are sometimes complicated to interpret if you don’t have some type of knowledge of training. At ROTOR we want to help you interpret the data in the easiest way possible, and we offer you the INpower application for free, so you can connect to your ROTOR watt meter and analyze all the training and competitions in the easiest and most efficient way.

Possible overtraining.

Many users who start training with powermeters experience over training problems, especially during the first months of use. Having the watts you generate available at all times can make you become obsessed, and put some figures in mind that are not realistic for your age, physical condition or training level. It is always very important that you value the physical level that you have, that you do not compare the data you generate with other riders or professionals, and that, if possible, use the help of a certified coach so that they can guide you when it comes to training in the most effective way.

Compatibilities and market options

There are currently many options on the market, and sometimes depending on which models you choose, you may have incompatibility issues between Bluetooth or ANT + connection systems and possibly, problems when the system you use is not compatible with the bottom bracket or crankset fitted to your bike. In this case, with ROTOR it is very easy to swap your ROTOR powermeter between one bike and another due to the high compatibility of our systems and the availability of adapters for different types of cranksets and bottom brackets.


Currently, the market has been constantly adapting prices of powermeters due to the many options available. In this sense the investment is big, but the improvements that you will get training with them are significant. You also have to assess that if you use 2 or 3 different bikes to train and compete, the final price can be increased depending on the type of system you use. One way or another, here at ROTOR we encourage you to introduce the use of powermeters in your workouts and competitions, if you are a medium-high user, looking for a progression in the quality of your workouts and / or competitions.
