Slipping chain qeustion

After an altercation with a branch the other day, i have replaced my rear derailleur and chain. The chain is now slipping a bit. I am told this is a worn cassete which now manifests that the old chain is gone. My qeustion is this: is there any way this slipping could be due to inept methods on my part? Being a newbie and i ride 40 miles every day to work, just wanted to get opinions.

Thanks for your time.

If you bent the RDER hanger, the RDER might be misaligned.
Eyeball the guide pulley to see if it lines up with the cog for each specific gear. (largest & smallest cogs)

and a worn cassette/freewheel teeth mis-match with new chains are a common source of skipping issues

Usually new chain/old cog skip is limited to the cogs that are most used or are the smaller ones but not all the cogs. A bent hanger, off SIS cable adjustment, a bad chain link usually are a problem over the full range of the cassette. But since these are very easily seen they can be assessed and dealt with quickly. This is where the ability to get the bike off the ground helps a lot during the diagnosis stage. To be able to both pedal the bike and view the chain/cog meshing and der/cog plane from more then one angle helps to figure out what's going on. Andy.

Ok so i just had the chain going through the derailleur wrong. real smooth now. now that i look though, the teeth on the gear i was in when the stick attacked, the teeth are a little bent. But even that gear works fine.

All is well thanks for the tips.

The teeth are most likely intentionally "bent" to improve shifting.
Bikes: Old steel race bikes, old Cannondale race bikes, less old Cannondale race bike, crappy old mtn bike.
