I was riding the other day on my commute to uni. Enjoying the ride.... just as i reach the final turn, suddenly out of the blue, I felt a vibration in my bike that didn't feel quite right. Got off and took a look, and behold what i found... the bike chain had suddenly lost a lot of tension, to the point where I could actually lift it off.. Had to do an impromptu chain tensioning to get home, now it's pretty much sitting at the edge of the green range on the marker. Any thoughts on why that suddenly happened? The previous time i did the tension, it was fine and had no issues, and all the screws and nuts were tightened as needed, (about a month ago).Chain has been lubed and cleaned frequently. My suspicion is that the chain is wearing out and I need to get a new chain.
