This is the second chain and cassette I have replaced. Thought I would have the bike shop do the work although I have the tools to do it.
Their price was very good. I keep the chain pretty clean and lubricated and I consider myself lucky to have gone so long since I was told when I bought the bike from them that I would need to replace the cassette after just a few thousand miles which surprised me. But then before I retired and used my bike only for a short commute I never dealt with the mileage I now put on it. Have replaced chains and freewheels on older vintage bikes so have no concerns about my ability to do so. In the future I probably will replace it sooner. I like the feeling of new equipment functioning smoothly but up until the past few weeks when I started to get a little chain skip on the smaller gears I have had no problem. Riding along the coast there are a minimum of hills and I use the 3 smallest cogs the most.
