Weird noise from the pedals- i think..
Hi there, I'm riding a Giant Terrago 2, i've had it for about one year and so far i'm very satisfied with it.
Although i do have two problems. The first one is that the piece of metal that changes gear on the front of the bike is sliding against the chain when i'm on third gear. How can i fix this?
The second problem i have is something i really cant figure out what it could be. It's a noise that comes from the pedal compartment too. But it only makes the noise when i'm pedaling forward with my feet on the pedals. So if i pedal backwards or pedal with my hand holding the back wheel up from the ground. There's like a clicking noise, every time i the pedals are at 180 degrees with the right pedal forward it makes this noise. I really can't figure it out what it might be, but i have been looking at it while im biking and theres nothing sliding against the chain or something.
I'm sorry that it might be a bit hard to understand but i couldn't explain it in any better way.
Thanks in advance!

The thing that's rubbing your chain is the front derailleur cage and if it's rubbing the chain your derailleur needs some adjustment. It's relatively easy and there are a number of tutorials available on the internet, both video and text and photo.
I suggest you search under front derailleur adjustment tutorial or something similar and find some. You should read a few to get a get idea of how this is done, then give it a go.
Meanwhile the click is more tricky. It could be the perfectly normal click of the chain passing over the shifting gate (the cut-down tooth in one ot two places of the chainring). or it could be a loose crank (though that usually only clicks under a bit of load) or a pedal bearing, or a bottom bracket issue. These types of clicks could be normal or indicate a problem, and are often a royal PIA to diagnose correctly.
Given that you're fairly new to bike service, I suggest you let a shop mechanic check the click out, and while there you might let him adjust the front derailleur (though you should give that a try yourself first).
