Gears slipping on mtb

The gears on my specialized rockhopper are slipping like nobodies business. Im gonna bring it into the shop and have them tune it, but doesn anyone have any recommendations as to how to solve this problem?
 
your chain tention might be too low, your grears might be worn down, chain might be too rusty, any number of things
 
must be a specialized thing. My old hardrock used to slip sooo much, and resulted in ripping my shins apart
 
you haven't changed your chain enough

the teeth o nthe crank are wearing down

becuz you havent changed your chain, you know need a new crank and chain
 
just WD40 your chain and sprocket, make shure that the derailleur is lined up with the gear it says that its in, make shure taht everything is tight, and check to see if your gears are really worn down. if they r then that is your problem and you need ot buy new ones (dont worry there not very expensive)
 
it has nothing to do with it being a specialized. either you ran the same chain cogset for ages and then decided to change your chain or vice versa. you should change your chain every 600 miles or so or once a year depending on how much you ride. it could also be a stiff link in the chain
 
get three chains and alternate them every couple weeks... keeps it from happening unless its your cogs that are worn down
 
My bike deos it too... its something every bike deos. For me it's because my derailer is unalined and pointing outwards so im pretty much stuck in the seventh gear of my cassete unless I change it with my hand. There are many other reasons for it to happen, like:

-tension in chain being to tight

-tension in chain being to loose

-not enough oil on the chain

-either cassette or chain ring on crank rings stripped

-derailer un-aligned

Take it into a shop, they can solve the problem with ease.
 
don't put wd40 on it that encourages rust. there are going to be two little screws on the back of the derailleur which adjust the left and right tension. Flip your bike over(unless it has hydro brakes) and then just adjust these screws 1/4 turn at a time individually until your gears stop slipping.
 
Yea happpened me too. You have a kink/stiff link in your chain.

My stiff link resulted in me almost loosing my testicles. (The chain slipped and then I nutted myself on the frame.)rite in front of cameron McCaul
 
uuh... those are limit screws... don't mess with them unless you know exactly what they do. If you adjust them incorrectly, the chain can come off the cassette and either chew up your frame or chew up your hub and spokes.

Chain tension: Adjust using the B-tension screw. Screwing it in increases the tension on your derailleur.

Worn drivetrain: Replace the cassette, chain and chainrings. Replacing only one of them at a time will cause accelerated wear on the newest item.

Derailleur hanger alignment: Bring it to the shop, they should have a tool to realign the hanger

Shifter cable tension: Use the barrel adjuster on the derailleur and adjust it 1/4 turn at a time. You'll want the cable tension adjusted so that if you're in the 3rd gear (for example), both the jockey and tension pulleys are in line with the 3rd cassette cog. Unscrewing the barrel increases cable tension, screwing it in decreases tension.

Stiff Chain Link: Bend the chain laterally until the stiff link loosens up.

For chain maintenance, you should wash it with a chain cleaner and lube it with an appropriate chain lube. Dry lubes are the best as they don't pick up as much dust, but you do have to reapply it fairly often.
