Review: Stages Shimano LR – a Power Meter that Measures on Both Sides

When it comes to the question of which power meter is best suited for one's own purposes, the one- or two-sided measurement of power values is an important aspect. After all, a double-sided power meter like the Stages Shimano Ultegra LR reveals imbalances in the pedal stroke of both legs mercilessly. Because I had only used the one-sided rotor InPower on my previous bike, the opportunity to test the Stage LR on my new BMC Road machine was a welcome opportunity for me: After all, I have been riding with power meters for over four years and appreciate the increased training efficiency. But I've never been concerned about the imbalance of my legs...

My conclusion

After a test phase of more than two months with about 2000 km on asphalt and continued indoor use on the roll (on average three times a week; 60-90 minutes; of course on Zwift) I decided that I did not need the luxury of a double-sided power meter, given the even lateral distribution. But it is also clear: If the measurement result had been different, I would have done a lot to eliminate the unbalance. Why? I ride about 7000 km a year. This is not an exaggerated amount, but it is also not nothing. And every two years I take up a cycling challenge as a highlight in the form of a marathon. Therefore I appreciate the efficient training with a power meter very much. And to this efficiency I also count the targeted correction of an unbalanced pedal stroke. The Stages Shimano Ultegra LR allows you to adjust this very quickly - especially in view of the simple assembly.
