The PM on my trail bike died, and I don’t see a reason to replace it. The only time it was ever useful was when I tried doing workouts on it, but I just don’t do that. I use my other bikes for workouts. The data is absolutely garbage on that bike because of how I ride it.
The PM on my XC bike is only useful when I use it for training, but that’s also rare. Worthless for racing.
On my road bike, it’s great or training.
