2 weeks with the Assioma Duo power meter pedals

Now that I’ve been using the Assioma Duo pedals for a few weeks, I figure it’s time for a quick review. I picked the Duo’s over the more popular and mainstream Garmin Vector power meter pedals primarily because of price - $800 vs. $1000. The $200 saved is $200 I can put towards other equipment, like the Yahoo Kicker (recently purchased, review coming soon!). To make a long review very short, the Assioma Duos are rock solid and offer anything I could want in a pedal based power meter system.

The hardware


The pictures say just about everything there is to say when it comes to the Assioma Duo hardware. Basically, the power meter is sandwiched between the pedals and the cranks. Installation is accomplished with an extra long hex wrench, included with the pedals. Thankfully, installation torque is not at all important for power meter accuracy, giving these pedals a leg up over older Garmin units, for example.


One of the best features of these pedals, in my opinion, is that they are rechargeable. Battery life is quoted at 50 hours or so, which is definitely in line with what I’ve seen firsthand. There is an iphone/android app that lets you see the battery life, and put the pedals into “travel mode” where they do not automatically turn on when moved. More on the app later. Also, having a rechargeable battery means that the pedals can be fully sealed, increasing their weather resistance. All in all, I approve of the choice to make these pedals rechargeable, and see it as an advantage over the Garmin pedals that use replaceable batteries and have been known to have battery associated problems.

The software

When I opted for the Assioma pedals, built by an Italian brand relatively new to cycling hardware, I was not expecting good software. So when I opened up the Assioma app and paired with the pedals, I was pleasantly surprised at how easy the whole process was. The software is simple, but not in a limiting way. It gives you all of the information you need, allows you to toggle a few options, and even prompts you to update the pedal firmware when updates are available. A recent update allowed communication of power data from both pedals over a single Bluetooth Smart channel, a major upgrade that users have been asking for. I had zero problems setting the power meters up, and ANT+ connectivity with my Garmin 810 has been rock solid. In short, everything works great.

The plan

A bit of personal history: I was a collegiate bike racer at Dartmouth College since my freshman year, and fell in love with bike racing from the very beginning. Right before my Junior spring, I broke my left femur, and the muscle damage and atrophy put an end to my collegiate cycling career. Now, after some rehab and a few years of casual cycling and bike commuting, I am finally ready to get back to racing.

This power meter is a major step towards competitively cycling this Spring. Some would say that the Duo pedals are unnecessary, while a single sided power meter is more than enough (and costs far less). But for someone like me, who had a major injury on one side, left/right balance is a serious concern, and the Duo pedals are worth the investment.

New York City is getting slowly cooler, and I’ll soon be forced back to indoor training. To help with that, I picked up a Wahoo Kickr on ebay. I’ve never used an erg trainer before, and I’m looking forward to anything that might make indoor training more interesting. I’ve also grabbed a TrainerRoad subscription to add some structure to my training. Goal is to climb my way back up to Cat 3 in the next two years, by the time I graduate medical school. Time is always short, but cycling is something worth carving out time for.
