Shimano R9100-P Dura-Ace Effektmätare

Med Shimano R9100-P tvåsidiga effektmätare har Shimano levererat en högkvalitativ effektmätare till marknaden. Perfekt för dig som redan har ett 9100-vevparti så att du direkt kan föra över dreven från det gamla vevpartiet. När Shimano släpper nya produkter vet man säkert att de testats noggrant i så väl labb som fält och fungerar felfritt. Systemet är vattentätt i alla förhållanden. Batteriet är uppladdningsbart utan sladd och behöver därför inte tas ut. Ett fulladdat batteri varar i ca 300 timmar beroende på omständigheter. Fördelen att träna med en effektmätare är att siffrorna är relevanta för din prestation oavsett topografi, väderförhållanden eller underlag. Till skillnad från en pulsmätare som bara skvallrar om intensitet och därför är lätt att påverka, visar en effektmätare din prestation. Genom att kombinera båda två kan man på ett fullödigt sätt planera och analysera sin träning. Dura Ace R9100 mäter även kadens med en sensor som läser av mot en magnet. Mätningarna blir därför mycket noggrannare än med accelerometer som kan påverkas av vibrationer. Kan kopplas via både ANT+ och Bluetooth.

Obs: Levereras utan drev.

Advantages compared to heart rate monitors
The wattage (torque (force x crank length) x rpm) gives an objective picture of your muscular effort at each moment of your ride. This has great advantages in relatively short interval blocks, where heart rate monitors often fall short. Because while a heart rate monitor sometimes takes up to two minutes to reach the heart rate zone associated with your effort, assuming weather conditions or fatigue/health are not a factor, a power meter provides accurate feedback within five seconds. That way you won't risk overexertion during those short interval workouts. With a power meter, you know for sure what effort you are putting in - at any time. So you can set your own limits and your pace. Specific training is also possible, for example a sweet spot training for an optimal training effect. By keeping track of your Training Stress Score (TSS) and Intensity Factor (IF), you can determine your 'training stimulus'. With this information, you can create an accurate training schedule that will help you reach your goal. You'll also prevent overtraining by doing so.

Post Race Analysis
After each training session or race, you can use the Shimano power meter to analyze your progress in detail. You know exactly where you used power, how much and for how long. How did you handle your power at certain moments? Did you hit a wall? Did you have heavy legs? If so, where - and why? You'll find the answer in the results. You may discover that you got heavy legs because you were applying too much power at too low a cadence. Or maybe the workout was a success and you want to repeat it later, or parts of it. The power meter is a real inspiration. You can accurately measure your progress both indoors and outdoors, in training sessions and in races. And your trainer will be happy with it, too. He can tailor the training schedule exactly to fit your needs.

Integrated Into The Crank
The Shimano FC-R9100-P power meter is 100% reliable, fully integrated in the crank and waterproof under all conditions. You charge the built-in battery with a small magnetic adapter. The instant response system continuously collects accurate data on the power delivered in different heart rate zones. The system is easy to reset with a switch on the transmitter.
