2012 Pacific Chromium 24" multiple Problems

So I am brand new here (just registered a few minutes ago)and I already have problems with my Pacific Chromium 24"(2012 Model) the chain falls off and the brakes go crazy if I try to use them(squeally to the 10th power)and the brakes also wear excessivly fast, when I only use them at low speeds. I can get you a video if you like.

Did you buy it new and from where? IIRC, Pacific is one of the Department Store brands and it's very likely it was assembled by someone with little to no mechanical skill. You might try returning it to the selling dealer and see if they can do it right. Otherwise you have a few of choices:

Learn to adjust it yourself. This forum can help if you can be more specific about the problems.
Pay a real bike shop to adjust it properly
Find a co-op or similar place and have them help you do the required adjustments.

From your description, the shifting needs to be adjusted and that will require properly setting the derailleur's limit screws and cable tension. Also, the brakes need to be aligned and possibly toed in to reduce or stop the squealing.

I agree wholeheartedly with the above post, but this is the best part of his advice. See if there's a bike co-op, in your community. They can be hard to find because they describe themselves differently. You could also check for a local bike advocacy group, which might run a co-op or can steer you to one.

The reason why thise are so good for folks in your situation is you can get low cost service from a shop less likely to treat you as a second class citizen for having bought a dept store bike. Also most combine repairs and teaching, include some where they don't actually do repairs, but instead teach how, and walk you through doing it yourself. You both get the bike working right, and learn to do it yourself for the future, all for less than basic shop repair rates.

Thanks, I got the bike as a Christmas present, so IDK where its origins are, yes it is new, and it was assembled by my dad here at the old homestead.

Your Dad probably has excellent mechanical skills, generally, but does he work on bikes much?
Adjusting shifting systems and V-brakes can be challenging.

You didn't say WHERE the chain falls off? Front or rear?
You probably need to adjust the derailleur(s) for that.

You might look in the brakes section also.

Why would the brakes wear fast at slow speed, but not fast??

There should be two screws next to each other on the rear derailleur. They are called "limit" screws because they limit how far the RD can move side-to-side. One of them needs to be screwed in (clockwise) a little to keep the chain from going past the cog (rear gear). There may be an "L" and an "H" marking. The "L" (low) is for the largest cog; the "H" (high) is for the smallest. Screw the appropriate one in a little until the upper-pulley of the RD lines up under the cog.

Does the bike have painted steel rims? If so, it will eat brake pads.

Wow this is an old thread. The new news is that I ended up getting a new bike (Gravity FSX 2.0) And am much happier with it. Double Disk brakes, Thumb/Finger shifting, etc. It's loaded.
