New cassette (guess where this is heading)

Ok guys went from a 12-23 cassette to a 13-25. Chain is under 1500km old so I thought **** it I'm not gonna replace it. I've got it all going but I get a notchy feeling from the pedals in some gears now. Usually when the drive side is at 3pm. Any idea what is causing this/what I have done wrong? I also went from a wet lube to a dry lube as well at the same time.

Thanks

if you never had the notchy feeling before the cassette swap, i'd suggest getting a new chain to get go with new cassette. besides, you don't want the old chain to wear out the cassette prematurely. and a new chain is less than 20 bucks. this is assuming that the new cassette is compatible with shifters(if it is index, and the spacing of old and new cassette is the same).

also, check the rear derailler adjustment. if it is index make sure the pulleys line up properly with with the cogs on each shift.

yep every thing lines up. I think it needs a few km under its belt.

Mileage means nothing, measure the chain for stretch/wear. That being said, chains are cheap so a new one isn't a big cash outlay. Didn't say whether you are running 10 or 9 speed, but 10 speed chains tend to wear quicker because they are thinner.

Chains should be replaced based on measurements, not mileage.
The notchy feeling could be a tight link in the chain, or a worn chain.

I bought a new bike changed the cassette the same day and got the same filling this is a new bike so I figured it was a bad cassette so exchanged it same thing took it to the place I bought it so they could look at it they came to the conclusion that the chain was bad the replaced it and all was good, this was a new chain. So it could be the chain.
