The new 4iiii Precision wattmeter of the 3rd generation is the result of the development and experience of the leader in the field of watt measurement on cranks. It is suitable for bikers who use a Shimano XT set and want to enjoy the benefits of power measurement without limitation. Compared to the previous generation, it brings several improvements - more compact, only 5.5 mm high body, designed for the vast majority of frames on the market, further up to 8x higher CR2032 battery capacity, stronger transmitting antenna for less interference, larger measurement range, etc. This package includes a left hand crank with a wattmeter installed, all ready to go.

  • Accuracy: 99%
  • Weight: only 9g on the left crank (the lightest mass-produced wattmeter)
  • Battery life (CR2032): up to 800 hours depending on ambient temperature (easy battery change without tools)
  • Integrated accelerometer for measuring cadence (tempo)
  • Wireless firmware updates via Bluetooth
  • Range of measured power: 0-4000 W
  • Range of measured cadence: 30-220 revolutions
  • Temperature with guaranteed accuracy: 0°C to +50°C
  • Storage temperature: -40°C to +60°C
  • Water resistance corresponding to the IPx7 standard
  • Compatible with ANT+ and Bluetooth 5.0 devices
  • Compact dimensions 63.79 x 26.42 x 5.5 mm

    SK Dobrý deň
    Chcel by som vás poprosiť o radu, čo je najlepšie ak som hobby jazdec a chcem wattmeter:
    - 4iii, ľavá kľuka, 175 mm
    - inpeak, ľavá kľuka 175
    - alebo investovač do Garmin XC 200
    - niečo ine?

    SK Dobry den,

    wattmetre v klukach su cenovo dostupnou alternativou urcit epostacujucou na hobby meranie - potrebne je overit len kompatibilitu s Vasim bicyklom - najcastejsie byva problemom priechodnost medzi klukou s wattmetrom a zadnou stavbou bicykla (postup v pripade 4iiii napr. tu: https://wwwold.4iiii.com/wp-content/uploads/2022/01/clearance-check-p3.pdf).

    Co sa tyka powermetru v pedaloch, napr. spominane Garmin Rally XC200 (https://www.mtbiker.sk/shop/komponenty/wattmetre/garmin-rally-xc-200-naslapne-pedale-s-wattmetrom.html) riesia problemy s kompatibilitou, kedze su absolutne univerzalne. Pri verzii so snimacni v oboch pedaloch ziskate naviac aj porovnanie medzi lavou a pravou nohou.

    SK Dobry den,

    ano, kluku mozete pouzit, dizajnovo to sice sediet nebude, ale funkcne to bude bez problemov - 4iiii powermeter v prevedeni M8100 je mozne pouzit aj s dalsimi MTB modelmi, napr. prave MT510, MT511 alebo MT512.

    Žiaľ kľuku FC-M7100 výrobca neponúka. Použiť je možné ale kľuku FC-M8100/M9100 - ak by ste mali záujem dajte vedieť a preveríme kedy budú dĺžky 170mm u dodávateľa naskladnené
