Does having a cadence sensor improve the accuracy of calorie calculations or other metrics?

I've been using my 840 more in my weight loss and fitness goals, and I was wondering if adding a cadence sensor to my bike would make the metrics, especially calorie calculations, more accurate.

  • a cadence sensor gives you accurate cadence data, nothing more :) a powermeter (which also gives you accurate cadence besides the power) can give you accuare data about the work (in kilojoules, which is ~1:1 ratio with calories if we assume 25% efficiency)

  • I appreciate the answer. I figured that, but wanted to confirm. I do have a cadence sensor on one of my bikes, but if it makes a difference, I would have added it to my other bike.

    A power meter would be wonderful, but just way outside my budget.

  • For a lot of cranks you will get a budget single crank arm PM upgrade.
    I*ve got a one for Rival around 200€.

    So it depends on the crank, as more expensive it is as more expensive the upgrade will be.

  • I'm riding a vintage MTB and a folding bike (both with flat pedals), so my options are limited. LOL
