Few problems, Newbie needs help
Ok so i guess ill start by saying i got the marin palisades bike a few weeks ago. after a bit of riding ive developed a few problems so here i go.
Derailleur: The chain rubs against the front derailleur when in certain gears. while it hasnt really affected me much yet its just kinda annoying hearing it rub against it.
Then today i was riding and as i was shifting my rear derailleur locked up as i shifted i think it might of been because i was pedaling to fast or because i was going uphill a little.
Bottom Bracket: i started to hear squeeking when i would pedal so once i got home i tried to figure where it was coming from so i found out it was my pedal area. I took off both my pedal post thing and twisted the bracket and it was squeeking. i put a bit of grease around it(Pedros All purpose xtra dry Syn Grease) hoping it would help but it didnt really
thats about it so far. if anybody knows anything, the advice would be much appreciated Thanks!
p.s. i weight 260 lbs. probably the biggest problem but im workin on it!

Being big will put more stress on your bike, obviously (I'm about 230 myself).
If you've just bought it, bring it back for a 'tune up'. New cables will stretch, even for featherweights. It should be part of your warantee to have a year's worth of checkup/tuneups. A stretched cable will change the position of your derailleurs.
You don't want that chain to be rubbing, aside from being annoying, it's causing unnecessary wear.
As for the creaking, again, I'd recommend returning it for the checkup. Cranks can come loose on new bikes, and you'll want to tighten that up ASAP.
Were any of these symptoms there when you first rode it?

Ditto on what Bugs said. Bring it back to the shop, tell them that the derailleurs need to be adjusted for cable stretch and ask them to just go through the bike and run a wrench over all the bolts. This shouldn't take them more than 15 minutes or so. As for the squeaking...are you saying that the bottom bracket itself is making the noise, or the pedal spindle? In either case, definitely have the shop get into it.
well when i first bought the bike i didnt have any of these problems. just started happening pretty recently.
As for the creaking its the bottom bracket itself. i took the pedal bars off and spun the thing inside which im guessing is the bracket. the link i put up had everyone saying its a piece of junk. so i thought it might be better to just replace it.
anyways thanks or the help guys!

Take the bike in for a tune. Also have them show you how to adjust the cables. It's pretty simple and can be done while riding.

I suspect that you either sucked a chain (near the crank) or you were riding in a small chainring/smaller cog combination and wrapped the chain around itself at the rear derailer. Or was it a case of the derailer just didn't shift? If that were the case the bike would have clattered and made a racket but didn't move the chain.
If the derailer just didn't shift, there are a couple of issues. One is that the cable needs adjustment which will be solved by the tune up. The other is pedal pressure. If you are climbing a hill and you are pedaling hard, the rear derailer may hesitate. You are putting a lot of torque on the chain and the cassette and depending on a little cable to work against all that. Don't keep mashing at the pedals trying to get the bike to shift. You need to ease up on the pressure just slightly after you punch the shift lever. The Shimano stuff isn't nearly as touchy as it used to be but you still need to ease up just a little.
If you sucked a chain, it's likely that you were shifting either up or down from the small chainring. A small burr on the ring or a bit of smutz in the chain may be the cause. If you sucked a chain, you'll see scratches on the chainstay next to the crank. If you do suck a chain...stop pedalling! You won't really damage much other then cosmetically, but you can really jam the chain in the gap and it's hard to get it out.
Finally, there's catching the chain on itself. This happens when you are riding in the small ring in the front and the small cog in the back. If you chain is long enough, you can end up rubbing the chain against itself in the derailer. If it happens to catch on itself, you can spin the derailer around the hanger and rip the whole thing off...that would be bad Don't ride in a small/small combination. You don't need to since there are lots of other gears that are of the same size.
