I recently was cycling, and in hard and steel pedaling my chain would skip. Climbing hills at every revolution it would skip.

So i thought it was the chain, i replaced the chain. And now its actually worse. Then i replaced the rear cassette and still nothing. Any ideas?

Last year it was fine. I havent been riding much this year, just got it out of the garage and started doign some cycling.

Any help would appreciated.

How old are your chain rings? Does it do it in all of your front rings?

rear deraileur out of adj? if there is not enough chain wrap, it can cause this symptom.

This seems obvious, but did you adjust the cable tension on the RD?

He said "Every revolution"

that means look to the front chainring

rear derailleur adjustment, sounds like to me.

unlikely that unless the chainrings were REALLY worn (also unlikley) it would cause skipping in the back.

where does it say skipping in the BACK?

Glad you guys are not doctors!

are you sure you used the correct kind of chain? is it the right length?

fixed

Thanks for all the suggestions. Im going to look into the rear derailleur adjustment. I dont know how to adjust it, but i will probably find a tutorial. My local bike shop wants 70$ for a tune up, and i just dont have the money right now.

The cassette is old, i took it from a older wheel. but it looks to be in good shape. The front chainring is old, but looks to be in good shape.

Hopefully i can get it going again so i can do my 50 mile commute again when the weather warms up.

Thanks for all the info! Definatly helps

here you go, it's not as complicated as it looks. bookmark the site.

you can change a cassette but don't know how to adjust a rear derailer?

I've had that happen to me before - chain would skip whenever I put big effort into pedaling. It turned out it was my bike frame and not the derailleur, nor the chain itself. The seatstays or chainstays had fatigued enough that it would not facilitate hard pedaling efforts no longer. This was when I was riding my Trek 2100 road bike - carbon tubes with aluminum.

So it may not be the components at all but your bike frame finally giving up.

If you used an old cassette, that's the problem. That cassette is probably worn out.

If you have a friend with a compatible wheel and up-to-date maintenance, swap it out real quick and see if that fixes it.

You can check the der fast by lining up your eye behind the bike, about 5 feet away. Have the chain in a middle cog, and site down the chain. You should see the upper pulley exactly lined up with the cog the chain's on, or maybe a teensy bit to the left of it.

If it's off, the barrel adjuster on the rear der works like a steering wheel: turn it right and the der goes to the right.
