Hi all who come here,
I am new to this forum, and I couldn't find a post about something I can't describe in words that well. I have bought a new mountain bike and straight away the bottom bracket kept coming loose. I kept complaining and the replaced it and all seems well with that. Now, there is a noise occurring when I try and put the power down going up a hill or something even slight too. This is a crackling sort of noise coming from either the front or back cog area, it happens on each revolution of the crank at the bottom of one of the pedals cycle. Is this normal? What should I and shouldn't I hear? It didn't do this when I got the bike, and it is kind of annoying. Any help would be appreciated.
