Gearless Crankset with Power Sensor

When I first considered this crankset, I expected it to be just another upgrade, but the reality has been transformative for my cycling routine. It helps me train smarter by providing clear data on my performance, and the lack of gears has eliminated a lot of the fiddly upkeep I used to deal with. As someone who values efficiency and learning, this has deepened my appreciation for the sport, making each ride feel more purposeful and enjoyable. It's not perfect, but it's a fantastic tool that has enhanced my time on the bike :)
- Pros: The power sensor gives incredibly precise feedback on my effort, making every ride more insightful. The gearless design means less maintenance and a smoother experience, which I appreciate as it keeps things simple and reliable. It fits well with my existing setup, connecting seamlessly to my cycling computer for a hassle-free integration.
- Cons: From what I feel, the crank length might not suit everyone, and it could be a bit pricey for some budgets. While it's built to last, I wish there was a bit more flexibility in adjustments to cater to different preferences without compromising on its solid construction.
