Bottom line, I had high expectations for this crankset based on the brand's reputation, and for the most part, it delivered. I was looking for something that would give me reliable power data to improve my cycling performance, and it does that very well. The reality is that it feels very solid and accurate, making my training sessions more productive. However, it did take a bit of getting used to, and the cost might be a barrier for some. Overall, it's a great addition to my bike, and I'd recommend it to others who are serious about cycling, though it's not perfect for everyone.
- Pros: The power measurements are incredibly precise, which has helped me train more effectively by focusing on my effort rather than just guessing. The build quality feels very durable, like it can handle rough rides without any issues, and the gear setup provides a smooth transition between speeds, making climbs and flats much easier to manage. It integrates seamlessly with my existing bike setup, and the courier called ahead for delivery, which was a nice touch.
- Cons: It could be a bit pricey for some budgets, and while the crank length is comfortable, it might not suit everyone's preferences without some adjustment. I could be wrong, but the installation required a bit more effort than I expected, and it took some time to get used to the data feedback during rides.
