- FEATURES -

IAV CYCLING DYNAMICS
Our power meter pedals provide advanced metrics called IAV (Instantaneous Angular Velocity) Cycling Dynamics: IAV Power Phase and IAV Rider Position. These metrics, combined with the classic power data, permit you to analyze your pedaling technique in detail and learn about how your position on the bike influences your performance.

IAV POWER AND GYROSCOPE
Assioma takes into account irregular pedaling (e.g. uphill, sprints) or the use of oval chainrings. Assioma can detect the actual instantaneous angular velocity during the whole pedal stroke, thus providing ±1% accuracy in any conditions.

 

BLUETOOTH AND ANT+
Assioma UNO pedals feature both Bluetooth and ANT+ connectivity for a seamless compatibility with bike computers and smartphones (both Android and iOS).

 

PEACE OF MIND
Favero offer 2-Year replacement warranty against defect.

 

EASY TO INSTALL. FAST TO MOVE BETWEEN BIKES.
Install and move your Assioma power meter from one bike to another just like a normal pedal, easily and without special tools.

 

MAKE THE MOST OF EVERY PEDAL STROKE.
To provide you with unprecedented detailed and precise data, the Assioma power sensors are placed on the pedals, exactly where your force goes. Pair it with your smartphone or bike computer instantly, using Bluetooth and ANT+ communication.

 

AUTOMATIC TEMPERATURE COMPENSATION
You can count on the most accurate and consistent real-time power data thanks to proprietary technologies, innovative software solutions and the advanced electronics of Assioma. Ride without fear in the snow, rain, mud, or sweltering heat: the automatic temperature compensation (ATC) ensures exact and reliable watt measurements in any weather conditions at temperatures between -10°C and 60°C.

 

WATERPROOF, RESISTANT ... AND THE LIGHTEST EVER MADE
The lightest and most compact pedal-based power meter: with no protruding elements, it does not interfere with the pedalling. Not even when cornering. Protected by a bi-component resin block, the power meter sensor is extremely resistant to shocks and fully waterproof.

 

USB RECHARGEABLE - WITH AUTOMATIC STANDBY
The lithium-ion technology provides a long battery life: up to 50 hrs with a single charge. You can recharge your cycling power meters simultaneously thanks to the battery charger with double USB cable and magnetic connectors.

After a few minutes of inactivity, Assioma automatically sets to stand-by and instantly switches on as soon as you start pedaling.

 

ASSIOMA APP - MANAGE WITH CONFIDENCE
With the Assioma App you can monitor the battery charge level, set crank-arm length, wirelessly update firmware, and keep up to date on new data analysis functions.

 

- MEASURED DATA -

  • Power - measures the power hundreds of times per second and continuously transmit the collected data to your bike computer or smartphone via Bluetooth and ANT + technology.
  • Cadence - indicates the number of revolutions made by the pedal in one minute (rpm). The in-built cadence sensor of Assioma constantly detects and transmits this value to the bike computer: making it therefore superfluous to use a separate cadence sensor.
  • Left/Right Balance (DUO only) - indicates, as a percentage, the power individually generated by the left leg and the right leg. The L/R Power Balance values allow you to monitor the dominant/non-dominant leg ratio and observe how this varies in relation to different racing and fitness conditions. This can be useful to correct penalizing imbalances: also in post-traumatic rehabilitation programs. Unlike others, the Assioma power meter pedals return these metrics through real dual-sided measurements, not estimates
  • Torque Efficiency (TE) - indicates, as a percentage, how much of the power generated during one pedal stroke actually contributed to the propulsion of the cyclist. A 100% Torque Effectiveness occurs when no Negative Power has been accumulated during a pedal stroke. The typical TE value may vary between 60% and 100%. Assioma UNO indicates the Torque Effectiveness value for the left leg; whereas Assioma DUO provides data for both left and right leg.
  • Pedal smoothness (PS) - indicates, as a percentage, how evenly distributed the power is in a full revolution of a pedal stroke. A value of 100% means that the power is delivered constantly throughout all the revolution: the higher the value the "rounder" the pedaling. Assioma UNO indicates the PS value of the left leg; whereas Assioma DUO provides separate data for both the left and the right leg.

Nice amplifier for the cost.
Style: Stereo Receiver, Configuration: Receiver
I had been using my Marantz model 22 receiver now for a couple years now with the TV, dvd player, and youtube music from my tablet. I like lots of knots and switches on my audio gear, I'm an engineer. I was getting tired of the seemingly endless up and down to adjust volume and whatever. And my inputs on the Marantz were maxed out. I searched Amazon to see what was available as a possible replacement that had a REMOTE. This Sony caught my eye. Relatively inexpensive, plenty of inputs, and specs I could trust, not a 3x4x5 box offering 220+220 watts of unlimited power! Ordered it and been using it for over a month now. Only 2 knobs, how good could that be? Well, it's remote let's me control everything without getting up. Plenty of output power, 100+100 watts of true RMS power. I didn't plan on using the Bluetooth but I tried it with the tablet, keeping the tablet by me, and it really impressed this old audiophile. I really don't have any negatives about it, even the fm sounds great. It was heavier than expected but not as much as that old Marantz. I even popped the cover. The build quality was what I consider good. I only wish I could find a service manual with the schematic for it.

Great Banana Plugs
Size: 6 Pairs / 12 pcs
I recently purchased these FosPower banana plugs to tidy up my speaker wiring, and they’ve been a significant improvement over bare wire ends. Installation is straightforward: strip the wire, loosen the two tiny set screws, slide the wire in, tighten everything down, and then screw the barrel back on. Once assembled, the connection feels secure and tight, making it much easier to swap gear around and reducing the risk of stray strands causing a short. The standout feature of this design is the dual set-screw clamp. It firmly grips the speaker wire without relying on the outer collar to “crush” it in place. I’m using 12-gauge wire, and it holds well for my setup. Initially, the plugs may fit snugly in some binding posts. Once seated, there’s no wobble, but it might take a bit of extra push the first time. The set screws are small, so a bit of precision is needed. Use a small flathead screwdriver and don’t over-tighten them. Overall, these plugs feel well-made, look clean once installed, and fulfill their purpose as banana plugs: making speaker connections quick, neat, and reliable.

Great Banana Plugs!
Size: 6 Pairs / 12 pcs
These FosPower banana plugs work very well. I have used dozens of these great FosPower banana plugs over the years, and they definitely work as advertised. When comparing apples to apples (or bananas in this case....lol), all Banana plugs work virtually the same way, and these banana plugs are no different. Strip speaker wire, unscrew banana plug cover, loosen speaker wire retaining screw(s), insert speaker wire, tighten speaker wire retaining screw(s), screw on banana plug cover, and wallah, a secure/conductive speaker/amplifier wire connector is created. Albeit, some banana plugs require the speaker wire to be splayed over a hollow post, and then they are held down by a screw-on retainer/cover. However, I much prefer these FosPower dual retaining screw type of banana plugs for their speaker wire holding ability. I always use high quality 14 gauge OFC speaker wire with these FosPower banana plugs, and they work perfectly together. I have used these FosPower banana plugs with many different speaker and amplifier brands over the years, including Klipsch, Pioneer, Polk, Denon, Dayton Audio, and Fosi with no problems at all. They just work, and work well. I have never had a FosPower banana plug break, release the speaker wire or short out, in all of the years that I have used them. Yes, these FosPower banana plugs do fit rather tightly into the connectors, at first, on a lot of speaker and amplifier brands/models. However, after the initial "squeeze" the banana plugs will lossen up, and become easier to install and remove. However, they still retain their great holding ability even after the initial squeeze. In order to overcome this initial "tightness," I usually just stick the FosPower banana plugs into a connector of an old portable amplifier, before assembling them, in order to squeeze them before inserting them into their final speaker or amplifier destinations. This is especially useful when working in tight places, where there is not much room to work in order to push the FosPower banana plugs into their tight connections firmly. Overall, I highly recommend these FosPower banana plugs. I am currently using them all over the house and shop for home theater and music listening (and testing projects). Just be aware of the tight fit in some speakers and amplifiers. Also, the 2 very tiny speaker wire retaining screws can be a challenge sometimes. Just use a good standard blade jewelers screwdriver, and be careful not to remove the retaining screws all of the way or over-tighten them. Once these things are mastered, using these FosPower banana plugs becomes second nature. Have fun!

The most legit banana plugs I could find on Amazon
Size: 6 Pairs / 12 pcs, Size: 6 Pairs / 12 pcs
NEW PREFACE:: I am kind of glad I first bought the horribly magnetic, horribly made and GOLD PAINTED Sewell crimp on plugs (some reviewers say that Sewell are better and easier to use than the FosPower, which is true in design, but in quality of materials FosPower beats them hands down!!) ... Changing from those to these FosPower plugs plus the Monoprice 90° plugs, I am flabbergasted at the difference they make in sound quality. I have heard people say that they can hear the difference and even as an audiophile I was skeptical..... but my skepticism has been completely erased by what I am hearing with my own ears. I waited a few days to make sure I wasn’t just tripping before updating this review 🤣....but it has become clear to me how much a difference plugs made from the right materials actually make!!! I am 100% serious that the bass coming out of my Polk Signature Series tower speakers has at least doubled at the same volume. I can also now turn the volume up Way past my max volume before, without any distortion and much more clarity and less harsh highs. Everything just sounds warmer in general now which is amazing!!!! This is dangerous info for me... because now I’m thinking about making some really nice custom wires to see how much of a difference that makes 🙄🙄🤣 OK onto the review of the actual plugs here~~ These seem like decent connectors. I can’t tell if they are brass or copper, but they only have a slight hint of a magnetic property when testing them with a very powerful magnet. I was easily able to fit x2 - 14ga wires into it for bi-wiring purposes, including screwing on the collar. (As seen in my example pic) The gold plating on the tips seems legit and not painted like some of the plugs from Sewell... I have tested and tried quite a few plugs from Amazon and most seem to be crap. These however hold up better than most! These and the Monoprice 90° banana plugs with the black and red rubber sleeves. The latter are gold plated copper and have zero magnetic properties. (if you need 90° banana plugs) UPDATE: still the best plugs I have found, but upon full install found two issues. One is a defect where a set of the plug threads for the barrel cover body weren’t cut right. The body’s do not tighten and stay loose because of that. Obvious issue for vibration with metal on metal... The other issue is that even though these say they can fit different gauge wires, they seem to be geared more towards 12 or 10 gauge. I am using semi solid strand 14 gauge and find that unless I fold the wire over to make it double thick, the bolts use up all the thread and seem to become kind of loose inside the body. They won’t fully seat and keep spinning no matter how much you tighten. They seem to stay secure still but I just wonder about longevity over time with vibrations. So I just doubled up the wire and they seated fine! Not the worst issue in the world, but just kind of a pain since you have to strip the wire longer than you normally would so you can fold it over. ANOTHER UPDATE: I had to remove these plugs from the wire to connect them to a crappy spring terminal amp while my better amp was in the shop. The issue I wrote about with the set screws "bottoming out" on smaller gauge wire became a more pronounced issue! I could not unscrew the set screws anymore and just had to cut the wires... So that means I will need to purchase more of these to replace the ones I cannot get wire back into. Not the best design, but still one of the best plugs I have found on Amazon.
