It's been well documented that Kenwood has an issue with Knolly (I can't remember what exactly the issue was). For his sake I hope he can move on and put it behind him. There are many people that love their Knolly bikes and time has proven the bikes to be tough, reliable, and exactly what some of us look for and value in a bike. It didn't work out for him, luckily there are plenty of other brands out there that he can find one that suits him. It's all choices, we can choose which bikes we ride, and we can choose to understand the world isn't perfect nor are we the center of it, and move on. We had a Subaru Outback that the engine overheated on a trip and needed a new one at 60,000 miles. We chose not to buy another Subaru, knowing full well they are very popular and reliable, but we chose to try something different. It's part of being an adult in this world.
I predict the new Endorphin comes out in 2022 and wins accolades around the industry. That's a very possible and reality based prognostication. A bike company suing over shoe rubber on leather is very unlikely, it would be more likely that a condom company would sue over that first.
