Bike is making noises at the back gear
#1
Why does my bike make rumbling noises when it is on speed 1 on the front and speed 1 on the back?
I have a GMC Denali 700c road bike and it has 21 speed. It only makes the rumbling sound when I am on speed 1 and 1 on both the front and back. Also, this is only the case when I flip my bike up side down to fix/inspect it. When I am riding it it does not make any noise on that gear and it seems fine. Is this normal? Why exactly is it making that noise? Im afraid I might damage the bike if I just leave it that way and keep riding. Also is there anyway to possibly fix this at home? Please help!!!

Probably the derailleur pulley is bumping against the large rear cog due to being upside down but it does not really matter if it doesn't happen when riding. Don't worry about it - ride.

I dunno? gravity is a funny thing, I could be riding upside down right now and not even know it! Mmmmm? Smile
If I ride in Australia, do I crash to the left or to the right?

Ha, of course not Nigel. It was just one of those pondering's like if move at the speed of light and turned on my headlights, would anything happen? I should have started a new thread I suppose. My bad!

Actually, it could be an important consideration for a trick rider......
