Reviews over the

Stages Ultegra R8000 Gen 3

I had a Tacx Neo home trainer to train with power before I decided to buy my first power meter for the road, and I was disappointed with this Stages L. In fact, it measured 10% less than my Tacx Neo home trainer, which is reputed to be very accurate (comparison of .fit files: https://www.zwiftpower.com/analysis.php?set_id=43823). The Stages application doesn't allow you to correct the measurement by calibrating with a static weight. That said, the measurement was fairly repeatable, so it can still be a good working tool, especially if you don't have another power source to compare it with (and if you don't compare yourself to others). This may have been an isolated case, as many people seem to be happy with this sensor. Thanks to Mantel I was able to return it: "30 days money back guarantee Our exclusive 30-day money-back guarantee applies to this product. This allows you to try the product for 30 days. If you are not satisfied with the purchase, you can return it within 30 days and you will be refunded. Even if the product has been used and tested by you. You are responsible for the cost of the return." After my return I switched to the Favero Assioma DUO sensor, and I have to say I don't regret spending more for this sensor and a power measurement on both sides. In terms of left/right balance I'm very close to 50/50 so the measurement problem with the Stages L was real and it wasn't a one-sided measurement problem.
