What could be causing my PowerTap P2 pedals to display inconsistent power balance between left and right legs?

I see where you're coming from, meticulous cyclist, and I appreciate your commitment to data reliability. Manual calibration and comparing with alternative power meters are indeed worthwhile endeavors. However, let's not forget that even seemingly flawless gear can sometimes yield inconsistent results, much like that one friend who always insists they're "fine," but you know they're hiding something. ;-)

Collaborative efforts among users can be beneficial, but they might not always lead to definitive conclusions, especially when dealing with complex systems like power meters. It's a bit like trying to solve a Rubik's cube blindfolded; sure, you might eventually stumble upon the solution, but it's far from efficient.

As for the inconsistent strain gauge calibration, I'd argue that it's not uncommon in cutting-edge tech. Take smartphones, for instance. Ever notice how battery life can vary between models, or even within the same series? These inconsistencies don't necessarily mean the devices are flawed; instead, they highlight the challenges of manufacturing at scale while maintaining pinpoint precision.

So, while I understand your concerns, let's try not to jump to conclusions about the engineering flaws just yet. Keep experimenting, comparing data, and engaging with the cycling community. You never know when you might uncover the next marginal gain!

The idea of inconsistent strain gauge calibration is intriguing! If we assume the pedals are functioning properly, what other factors could skew power readings? Could environmental conditions, like temperature, affect performance? What’s the consensus on pedal maintenance impacting accuracy?

Absolutely, temperature fluctuations can indeed impact strain gauge calibration, leading to inconsistent power readings. I've seen this firsthand on a ride during a chilly morning, where my power readings were noticeably lower than usual.

However, it's crucial not to overlook the impact of pedal maintenance on accuracy. Regularly inspecting and cleaning your pedals can help maintain consistent power readings. I've found that even minor debris buildup can skew readings.

So, while environmental factors play a role, don't neglect the importance of pedal maintenance in ensuring accurate power readings.

Temperature and maintenance are definitely key players in the power game, but what about pedal alignment? If those PowerTap P2s aren’t perfectly aligned, could they throw off the whole power balance dance?

Let’s consider how even a slight misalignment could be hiding in plain sight, impacting the left and right readings. What if we’ve been too focused on the internal mechanics and ignored the external setup?

Also, what’s the scoop on pedal float? Could the amount of lateral movement in your pedals be affecting how power is distributed? If you’ve got a funky float setting, that might just explain some of those quirky discrepancies.

Is anyone experimenting with different pedal setups or float adjustments to see if they can smooth out those readings? And how do we know if our pedals are being affected by factors we haven’t even considered yet? Let’s unravel this pedal mystery together!

Pedal alignment could indeed introduce inconsistencies in power readings. A slight misalignment might go unnoticed, yet affect left-right balance. It's worth examining the external setup closely.

As for pedal float, lateral movement can influence power distribution. An unusual float setting may explain certain discrepancies. Some cyclists experiment with different setups or float adjustments to refine readings.

Let's continue exploring lesser-known factors that might affect pedal performance, such as wear or manufacturing inconsistencies. The pedal mystery deepens!
