I am finding it very annoying on my new Norco Tactik hardtail that the chain seems to bounce around a hell of alot! It makes alot of noise and comes off and gets caught alot too. My buddy has a kona shred and there is barely any bounce. Any ideas?

You need to shorten the chain by a few links.

how abouts may i go about that

You need a chain breaker and a way to figure out how many links need to be removed.

Kona...how do you figure that out? is there a number you can go by using the maximum number of teeth you have on combined top rings

For Levi's case I would remove 5 links first to see if that helps, if not, then 10.

that seems like a lot to me. I mean if it works it can't be that much too long. I would think only 2-5 links myself.

I am saying 5-10 because the tactic uses short chain stays. Out of the two I gave, I think it will be the 5 that solves it.

I would put it in the largest chainring and largest sproket, and take out enough links to make the derailleur a 45 degree angle with the ground. Then, get yourself a lizard skin chainstay shield.

you know parktool truely is amazing
heres one for removing and puting a chain back on
and heres one for chain sizing(length)
theres even a formula

the park link is very helpful.
There are mathematical forumulas but not worth the time. Just use the small small/big big technique they explained and when removing links...be conservative. I never take off more than 2 at a time unless its a brand new chain in which case they are usually fairly oversized.

would they do all that at the bike shop, any ideas on how much it might be?

More than you need to pay. It is so simple, especially if you don't have a Sh*tmano chain. They should have done it when they assembled the bike, but I would do as much work on your own as possible. 40 bucks an hour for labor is rediculous.

yea a chain tool can be aquired for under 10 dollars, it takes no genius to figure it out.
