I have bought a bike few days ago and I am a new rider as an adult. And, I am a little confused as my rear brake has 7 cogs but the chain is on the second from top cog.
Shouldnt it be on the biggest cog in gear in 1? If so how would I fix this?
Similarly, the indicator looks like it is in between gear 1 and 2.
The front cog when in gear 2 also makes a grinding noise.
Please help me, I am a newbie and would appreciate the help.
**UPDATE: Adjusting the front derailleur **
I have followed accordingly, as per answer below, and found on the front cog the chain looks to be scraping against the second/middle cog of the front three.
Putting the Front gear in 2 and spinning the pedals the chain doesn't go in the second cog. But, when I was riding it this morning, felt like I was in gear 2 for this gear.
Also, trying to adjust the derailleur on on the vertical axis - up and down; the screw seems like it is just spinning and no movement. I can easily see the horizontal movement just not the vertical.
I am lost as to what else needs to be done now.
