Before I got this, my rides felt a bit rough and I never knew how hard I was pushing myself. Now, it's like having a little coach with me—the performance insights are super helpful, and everything feels more efficient. I'm really enjoying how it simplifies things while still giving me what I need to improve. It's made cycling more fun and effective for me! 😊
- Pros: This crankset is a game changer for my rides; it fits my bike perfectly and feels just right, making pedaling smoother and easier. I love how it gives me accurate feedback on my effort, helping me train smarter without overcomplicating things.
- Cons: It could be a bit pricey for my budget, and I'm not entirely sure if it's the best value, but it's fairly good overall.
