While I understand the concerns about non-locking grips on mountain bikes, I think it's important to consider the full picture before dismissing them outright. Yes, non-locking grips may have a higher risk of grip failure and loss of control compared to locking grips, especially during aggressive riding. However, it's also important to note that many riders prefer the feel and adjustability of non-locking grips, and may even find them more comfortable for long rides.
Furthermore, the perceived benefits of reduced weight and cost savings should not be dismissed. Every gram of weight saved on a bike can make a difference in performance, and for many riders, the cost of their equipment is a significant factor in their purchasing decisions.
That being said, I do agree that safety should always be a top priority. If non-locking grips are causing riders to feel unsafe or uncomfortable, then it's worth exploring alternative options. However, rather than vilifying the entire category of non-locking grips, I would suggest that riders and manufacturers work together to find solutions that meet the needs of all riders. This could include developing new grip designs that offer the benefits of non-locking grips while also addressing concerns about safety and performance.
Ultimately, I believe that the industry can and should do better when it comes to providing safe and high-performing equipment for all riders. But let's approach this conversation with a spirit of collaboration and open-mindedness, rather than resorting to finger-pointing and assumptions.
