are now several years that have been introduced on the market, renowned names such as SRM populate the numerous bicycles and not only professionals, others as the CYCLE OPS with his POWER TAP or the new power2max were joined over time, what about the first and last rely on detecting the power by turning the crank, SRM measures power in watts directly on the bike during training and competitions, that under real conditions. The power is measured at the point where you can measure to better: the transition between cranks and sprockets. The power is measured continuously and not, as in other systems, only on one side only with every turn of the crank or even less frequently. The measurement is not consistently inaccurate and gives a wrong picture of the state of training of the rider, with negative consequences in the long run.
both ( SRM / POWER TAP / power2max and working wireless and compatible reading from the systems Ant +)
L ' ANT + is the standard guaranteed power2max compatible for all the bikes and computers, eg: Garmin Edge 500 and 705, O-synce MACRO X short I think the Edge 800 also implement
still just go on the site ant:

and here you can see by selecting the make and model of your cycle computer if it uses the protocol ANT +
The Powermeter SRM is mounted instead of the usual combination crank / chainring as well as the power2max while POWER TAP is nothing but a hub is housed in particular where all that will measure the power.
Then we have a new generation of power meters that rely on pedals where to measure the power ( that calculates the power cyclist measuring force applied to the pedals ) including the MetriGear acquired a few months after GARMIN , or the Polar-Look, which should be presented this spring as Garmin almost certainly by the middle 2011 should show its new product. Just to note is the PIONIEER still in testing and should hit the market next year very interesting device as it offers a measurement on the crank without as being intrusive or SRM power2max level implementation of the device.
- independent measure of the pair L / R
- ANT + compatible
- console based on Android with GPS, mapping and 2.2 inch LCD
The parameter of power is increasingly becoming a central value in ' training of both cyclists professionals and advanced amateurs, as you'll see over the age of cardio, or rather implementing the power has come to have a much higher precision in the analysis of their performance, ensuring each training session is fall deeper in the quality of training.
We see a little better this concept, the power meter is a very useful tool that helps a lot if used well in accomplishing the repetitive gesture of training and brings the best results, the heart rate is not a precise number because it represents an internal load that can vary by many factors / variables such as stress (daily every hour are not the same), the temperature as you sleep at night, L ' altitude is different if we're riding in the mountains compared to our usual level of outputs sea \u200b\u200b as our way of life, cycling position, dehydration. Power is a external load that did not change, then the power remains the same. In addition, the heart rate
Heart rate, however, is not to be missed, it becomes a control parameter, very important so it will certainly disappear.
What prices are we talking about? of several hundred pieces € .... for example ' SRM from 2500 to 3500 for bdc for mtb, price that puts it on a level I would say almost cost prohibitive for a town bike lovers, the tap power from 1300 to 1600 for bdc € or MTB, power2max us on 850 - 1100euro depending on the choice crankset. Polar-Look on the U.S. market should essre on the proposed 2200 - 2500 dollari however it is still early to have precise data.
Garmin has announced plans to launch the product at a competitive price and expand the audience for this type of instruments, we hope that the price would fall significantly below the 1000 euro which makes it usable by the mass of cyclists and wheels fat than those of the bike race, but once again better to be patient and not expect too much in terms of prices.
soon with more updates as they become available.
