Riding Game Changer
by mparic

I don't race so there's no need to have dual-sided meters (to track 50/50 power distribution) that are more expensive or prone to breakage (I'm looking at you, pedals). After a winter training on Zwift and Kickr, this power meter allows me to transfer all that hard work during the off-season into quantifiable gains on the road. Super easy to install and pair with my Garmin 530. Instead of watching distance and speed on my Garmin, I use a screen that has cadence (did I mention it works as a cadence sensor too?), heart rate and watt output. These stats keep me in the correct zone for the type of route I'm riding (short and hilly, metric, century or beyond). A power meter both on my trainer and road bike has been a game changer for me as I broke all my PRs within the first few weeks of the season.

Excellent Power Meter!

The power meter as a piece of cake to install, taking about 5min., just remove the old arm and replace it with the new one. And, it effortlessly paired with my tablet, iPhone and Garmin Edge 530. There have been 2 firmware updates and neither was any problem. The power and cadence data has been reliable on every ride I�ve taken. Having accurate power measurements is helping me improve my cycling performance.
