INpower / 2INpower: 5 reasons for fitting the best technology to your bottom bracket

Installing a powermeter to our bike is something more users are thinking about. Powermeters are no longer exclusive to professionals; fitting one to your bike will help your train better, plan your training better, and your season better. At ROTOR, with our range of INpower and 2INpower we offer you some of the best options on the market. These are the 5 reasons why you have to try ROTOR´s powermeters. 

Plan your training & season

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

In the case of the INpower system, power is measured in the left leg through two sets of opposite on-axis meters that deliver accurate data metrics, including power output, cadence, torque effectiveness, and smoothness of pedaling.

Measuring DATA from both legs

Powermeter systems such us as the ROTOR 2INpower or INpower allows you to measure in real time the intensity and the watts of work generated by both legs independently (only 2INpower). This is very useful at the level or egononomics on the bike and biomechanics, to find the most effective position on the bike and achieve a total balance between both legs when it comes to putting force on the pedals.

Within all the parameters that we take into account when we use a powermeter,watts, cadence, power applied in the pedaling cycle, we can also know how many watts we apply on average and how we use them with respect to our left and right legs. In this sense, systems such as the ROTOR 2INpower, allow you to know the independent power of each leg, which will help you improve training, as well as the biomechanics of pedaling. ROTOR´s INpower systems  have the cadence sensor built into the crank so, you do not have to install any extra sensors and it iscompatible with ANT+ or Bluetooth Smart systems.

Reliability: Using power as a measuring base

If you are used to training in recent years based on heart rate, the jump to the level of reliability when training with a powermeter is huge. The accuracy in the measurement of your heart rate can be affected by many values, such as heat, tension, stress, time of day... This means that, although cardiac control is something to keep in mind in training, especially to monitor possible periods of overtraining, the powermeter is much more exact since it tells us the real power that we are applying to the pedals at all times. 

In addition, another of the key points is to be able to store training data through ROTOR´s INpower and 2INpower powermeters is the specific ROTOR POWER app, with which you can use a smartphone as a screen, where among other options you can view the power, cadence, pedaling smoothness or torque effectiveness data. 

Combine them with the chainrings of your choice

Both ROTOR powermeter systems start with the advantage that they are installed to your cranks/BB, this means you can use the ROTOR chainrings and the ROTOR chainring anchor system that best suits your needs. Something that is valid for both mountain and road. You can choose oval or round chainrings, DM chainrings, OCP... In this way, you have a total range of choice, not only of bottom bracket and crank length, but of chainrings/ chainrings. 

Compatibility of cranks and bottom brackets

One of the key points of the INpower and 2INpower systems is the compatibility with the different types of bottom bracket, chainrings and crank lengths. At ROTOR we make it very easy for you to install any of our INpower systems, as they are compatible with BB30, PF30, PF30 BBright, BB386, BSA, ITA and BB86 type bottom brackets (in MTB; BB30, Pressfit 30, BSA, BB89 and BB92). In addition, the following road crank lengths are available; 165mm, 170mm, 172.5mm and 175mm, and 165, 170 and 175mm for MTB. Both INpower and 2INpower systems connect to all kinds of external devices through ANT + and Bluetooth Smart protocols. The battery life of the INpower system is up to 300 hours, while that of the 2INpower is about 250 hours of use.

The powermeter is something that is becoming more widespread in non-professional cyclists looking to improve their workouts with the help of technology. Analyzing the pedaling, knowing the power we apply, improving the cadence, or simply seeing the evolution of our contribution in watts at moments of maximum power, are essential to improve our training. You just have to decide on the INpower from 729€ or the 2INpower from 1.199€.
