I have had my chainlift tool for a few months now. I have used it more than I thought. The chainlift tool has allowed me to make quick, easier, and cleaner transitions between riding outdoors and outdoors. The weather during the shoulder seasons in the Pacific Northwest is unpredictable. We go through a period of "do I ride on the trainer today" or "do I get outside?". With the chainlift, due to how much easier it is to transition from bike to trainer and from trainer to bike, for me it eliminates the excuse of not riding one way or the other. I do recommend you watch the videos for instruction. I use it on both my wired & wireless derailleurs with no problems. If you are a DIY bike mechanic like me and you use a trainer in inclement weather, I highly recommend the chainlift too.
