Mountain Bike making strange popping noise when pedaling in lower gears
So for the past few months, my Mountain Bike has been making some weird popping noises when pedaling in the lowest gears, to be specific, 6 and 7, I have no other problems with the other gears.
I don't really go off road much anymore, and this is becoming an annoying occurrence, below I have a video of it.
Sorry for the quality of the video, by the way - I recorded it on my phone.
Does anyone know what this is?
I'd like to note that I don't really think it's a worn part issue as this bike is not even a year old, but I don't know.
