I just got a pacific dart 21 speed mountain bike from a friend. I need an owners manual for it

SOURCE: How can I raise handlebars on a 26 in. Mountain

You need an Allen wrench (a.k.a. hex key) to fit the bolt head right in the middle of the handle bars. Loosen this bolt just 2 or 3 turns then tap the head with a soft hammer or block of wood and a hammer. Then pull the handle bar stem up (and all of the way out so you can see how the wedge-shaped nut at the bottom of the stem works). Look for a mark on the stem telling you how high you can safely raise the bars (you have to leave enough of the stem inside the tube so that it will be strong.) Put it back in and tighten it up. If you found this helpful, please vote. Good luck

Hi.

If the chain slips when the bicycle is in high gear you need to align the rear derailleur hanger. See the picture below:

You haven't actually asked a question, so I am guessing that you want to know how to replace a bicycle chain on a 21 speed bike. To remove the chain you need to use a chain tool that presses one of the pins out of the one of the chain links (any link, there is no master link). To put the new chain on you use the chain tool to press the pin in. This is just a little tricky with a chain tool, but it's just about impossible without it. They sell these tools at bike shops and maybe even at Wal-mart. Take a look at this link to see a what I'm talking about. http://www.parktool.com/blog/repair-help/chain-installation-derailleur-bikes By the way, Park tools are very good quality for the money.
