Replacing bicycle chain and freewheel

It’s that time of year again. I seem to be repeatedly doing the same thing without learning. Found that the chain on my bike was slipping, replaced with a new set of chain, and then found that it was slipping even more. Sounds familiar. Checked my blog, and this happened just less than four years ago. Because I thought I have “just” replaced my freewheel, I thought it is the front chainset that needed replacing instead. Went to the bike shop, luckily this time it’s just down the road, the shopkeeper told me that every time I replace my chain I should replace the freewheel as well, otherwise the chain will slip. Looks like I have worn out the freewheel once again. Probably should have just replaced the chain every one or two years. As it turns out that it is such an expensive exercise having to replace the chain and the freewheel together every time! But I seem to remember my colleague suggested to me before that a general guideline of his is to replace the chain every 5000 miles. Looks like since I don’t really take care of my bike, and don’t keep track of how many miles I’ve covered, I should just come up with my own rule and replace the chain every one and a half year instead. OK, this post shall mark the day on which and I replaced the chain. Let’s see if I can remember…
