My bicycle grinds or something when in first gear?
Alright so I just got a brand new 21 speed bike(3 on left, 7 on right), and I'm not totally sure how to shift gears.. What I'm understanding is that low gears(1 on left, 1-2, maybe 3 on right) are for going uphill, while 2-3 and 3/4 - 7 are for going on flat ground or downhill... What I don't really understand is how to determine whether to switch the left or right shifter... For instance, today I was going down a hill, not very steep at all. I think I was in 3rd gear and probably like 5th or 6th on the right. Then, when I started going uphill(same hill, I just turned around to go home), I switched gears to lower numbers... since then, whenever I go into 1st gear on the left, it makes a constant grinding like its changing gears. I was kinda embarassed if anyone was around lol, so i kept it in 2nd to get home..
What's wrong???

Yeah, but what kind of bike & from where? If you bought it at a discount store, they just slap 'em together in about 15 minutes. They never (and I do mean NEVER) give the bike a thorough TUNE-UP as real bike shops do. REAL bike shops have qualified mechanics who take up to an hour (or more) to assemble & check everything.
Real bike shop? Take it back. It's under WARRANTY. Discount store bike? Still - take it to a bike shop. Tune-ups generally run around $60.

Small chain ring in front goes with 1-4 in rear, middle chain ring in front can sweep 1-7 in rear , and largest chain ring in front 4-7 in rear.
