| Nov 1, 2016 at 22:51 | comment | added | alexsimmons | OraNob - It's clear you did not read the link I provided. Please read it first before telling me what I already know and have taken the time to explain in a manner that can't be done in a comment. I voted on your answer accordingly as it contains factual errors and is misleading, not because it's not what someone wanted to hear. | |
| Nov 1, 2016 at 22:11 | comment | added | OraNob | And as for describing my response as "low quality" - I can only measure that response from the OP as my answer not being the answer he wanted to read. | |
| Nov 1, 2016 at 22:09 | comment | added | OraNob | "Allen says, ‘The true left and right meters now, as far as I know, are the Garmin pedals, the Powertap pedals, the Infocrank and also the Pioneer crank.’" quoted by Allen from the same article. And if twin strain gauges is the only true measurement AND each strain gauge will have a quoted accuracy of X% - a valid question & point is how accurate is a measurement of pedal asymmetry - if you are only staring at power? And if you don't have twin strain gauges in your hardware. | |
| Nov 1, 2016 at 22:01 | comment | added | OraNob | cyclist.co.uk/news/1416/… "When the strain gauges of a power meter are placed at the crank spider, hub or chainring it is difficult to isolate the forces each leg is applying individually. These systems largely generate a balance figure by separating the power in the first 180° of the crank rotation from the power in the second 180° of the rotation, and calculating a consequent balance between the two. That’s a fairly accurate measure, but does not fully consider that a rider may be exerting force on the upstroke." | |
| Nov 1, 2016 at 21:36 | comment | added | alexsimmons | OraNob: i. as RChung pointed out, your use of the term "single-sided" is misleading. There are 2 ways to measure total (both legs) power, each based on location of force measurement (upstream or downstream of bottom bracket), see: alex-cycle.blogspot.com.au/2013/11/… single sided = upstream on one side only ii. pedalling asymmetry & variable asymmetry is normal, hence true single sided meters can never be consistent; iii. you can't infer pedalling style from the OP's data. Such data does not have the temporal resolution to enable such an assessment. | |

| Nov 1, 2016 at 13:15 | comment | added | OraNob | Well hopefully you can concentrate more on turning circles instead of right-leg squares. Best wishes. | |

| Oct 31, 2016 at 22:25 | comment | added | R. Chung | I'm not sure what you mean by "year dot." In the context of Azul Shiva's question about bilateral asymmetry, the SRM, for example, is not "single-sided." It may be mounted on one side of the bike but it measures total combined power generated by both legs, not just the left or right legs. Power meters that exclusively use sensors mounted in the BB, the left crank, or the left pedal are often referred to as "single-sided." | |
| Oct 31, 2016 at 13:06 | comment | added | OraNob | Your assertion and analogy is just wrong. You are assuming a 100% dead-spot in power for the opposite leg (on the up stroke) at the point your driving leg (on the down stroke) makes maximum power. If you have ever done single leg drills - you will really notice how much the opposite leg contributes to the full stroke of the other leg. Besides - you should not be consciously riding to target a specific side because you know a power meter is on that side. That is not the way to train with a power meter. | |
| Oct 31, 2016 at 12:54 | comment | added | AzulShiva | The problem with Power meters that only measure Power on one side is that the other leg becomes irrelevant. Wether you're doing 52/48, 60/40 or 90/10. If you rode to power on your right leg and an alligator bit your other leg off you wouldn't even notice regarding Power. And the problem I have stated is that when you ride with one sided power meters you will unvoluntarily end up doing 55/45 because that is what the power meter has trained you to do and you will end up a miserable cyclist. | |

| Oct 31, 2016 at 12:39 | comment | added | OraNob | Read the answer - all of it is relevant to your question Single-sided power meters are used due to economics of producing dual-sided strain gauges. And they offer consistency / precision of reading - which is the one of the most important aspects of the tool (unless you are comparing data from rider to rider). | |
