NGeco Rotor ALDHU24 power meter set Road

pprendeville

Anyone got one of these powermeters? i read in the past they are very reliable. I have a Shimano chainset so this is compatible.

Does BLE mean bluetooth? Are there different types of bluetooth?
Anyone have issues with Water Risistance on them?
Do you really get 300 hours out of the battery?
Is there some sort of low battery indicator?
Does it require calibration before each ride?
What is pedal smoothness and how would this metric be indicated?

Bluetooth Low Energy, its a special mode of bluetooth 4 onwards for small devices like heart rate monitors, watches, power meters etc. Any modern bluetooth device will support it.

I don't have this particular power meter but from my understanding every power meter should really be "calibrated" before each ride. Power meter design and implementations have improved to the point that the likes of temperature has less of an effect these days (or, in some cases, the meter itself actively adjusts for it), some claim to be immune to temperature changes in fact, but I believe that calibration is still always recommended every time.

I think that need makes more sense when you think of what this "calibration" is. It's not actually calibration at all, true calibration requires suitable equipment to ensure the power meter is measuring accurately, not a simple or quick task.

Instead, what is typically referred to as "calibration" is actually determining the "zero offset", or reference, value of the power meter i.e. measuring the torque of the power meter when no torque is actually being applied by the rider. If this figure is wrong, then the power figures reported by the power meter will be wrong.

In order for this reading to be reliable, you need to ensure that you are not applying any pressure to the power meter when doing this "calibration" - I do the measure without my feet clipped into the pedals, for example. It takes about 5 seconds in my case, so not a headache at all I just have to remind myself to do it.

It's a measure of how smoothly/consistently you apply power to the pedal throughout a revolution. Theoretically it should help you develop a more efficient pedalling style, if you can measure and understand the figures. Personally I've only toyed with that aspect of my own power meter (pedals), I keep telling myself that I'll sit down and make an effort to analyse and understand the figures in order to learn from them and improve, but I've yet to do it - don't be like me!

I see that pedal smoothness is an optional extra for that power meter, so will cost extra. Worth checking too if the head unit you'll use to display your power meter figures supports the display (and recording) of pedal smoothness (and any other interesting measures that you want to view), not all of them will necessarily do so.

Also, depending on where you like to upload your ride files to, you might not get any post-ride reporting of such metrics either. As an example, I primarily use both Garmin Connect and Strava to analyse my rides, and while my pedals supply pedal smoothness data and my Wahoo Elemnt Bolt records (and can display) the data neither of those two services support pedal smoothness so they just ignore that data.

Does BLE mean bluetooth? Are there different types of bluetooth? Your phone/headunit will pick up the bluetooth signal
Anyone have issues with Water Risistance on them? Haven't done enough wet spins with it yet but have had no issues and haven't seen any reports of problems online
Do you really get 300 hours out of the battery? I'm sure it'll be less than the manufactuer claim when in the real world but its simple to change and can be done in 30 seconds, just remove a rubber cover and pop in new battery and replace rubber cover. No tools etc needed
Is there some sort of low battery indicator? There is an led on the unit which I think shows if battery is low when you first spin it. Garmin head units will also show a low battery warning, I'd say wahoo etc would as well
Does it require calibration before each ride? I do it but P2M zero offset if you stop pedaling for ~ 3 secs so it zero offsets itself. I zero offset at the start of each ride just to check the offset reading is in line with the normal reading
What is pedal smoothness and how would this metric be indicated?

To be honest I'm not sure most joe averages would get any benefit from it, guessing more use to TT/triathletes. I think you pay extra on the Eco for that but is free on the TypeS
