After seeing this on SM, I explored the website and watched the videos. While the cost is significant, I decided to try it out. The ordering was easy, it shipped immediately, and it was evident that there is great care in the company for its product and their customers. When I received it two days later, I tried it on my road bike on my bike work stand. As the website says, Chainlift is not intuitive to use, but once you figure it out it works well. The particular pin for my derailleur was the shortest, and it didn't seat snugly but was OK. I watched the video again and paused for each step for my initial use. Finally, it all clicked in my brain, and I felt quite pleased with my decision to try it out. I will only use it for routine maintenance, and I don't expect I will get my wife to use it without me, however, it is clearly well made and I expect it will provide satisfaction every time I use it. I just need to remember how!
