Keenso Rear Derailleurs Editorial Review
The Keenso Rear Derailleur Extension Tail Hook has received a mixed reception among cycling enthusiasts, primarily noted for its practicality and the flexibility it offers in upgrading bike components. Many users appreciate its ability to lower the rear derailleur by 15-18mm, which allows for the utilization of larger cassettes, enhancing the versatility of mountain and road bikes alike. For instance, those who have updated older bikes, like a 2012 Trek Superfly, found it beneficial for converting from a 3x10 to 1x10 setup, expanding their gear range significantly. However, there are concerns regarding quality control, with some users reporting that the part was not properly machined, making it difficult to fit without modification. In contrast, users who received a well-machined product reported a stable and reliable performance, specifically in adapting to larger sprockets without compromising function. Feedback also reflects an awareness of the price point being slightly high for a component of its size, though some justify this expense based on its sturdiness and functionality. Overall, while the Keenso extension offers significant enhancements for some users, the variability in manufacturing quality has led to a divided reception. Those who receive a well-finished product tend to have a positive experience, while others express frustration over the need for adjustments. **
