Need some advice on chain slip.

Hi,

I have noticed that the chain on my MTB (3x8 setup) slips quite frequently especially when going uphill, or when pressure is applied on the pedals. This happens mostly on 5 & 6 gears. I have never replaced the chain or the cassette, it has run for 2200 KM so far.

The ruler test on the chain indicates some chain wear. Please see posted photos.
1. Do the chain & cassette need replacing?

2. Gear shifting is also not very smooth, do you think I should sort that out first, or do the chain & cassette need replacing first?

Thanks
a

    Well going by the measurements the chain has stretched. If you are getting slipping in two gears they are probably the most used and are the most worn. It would be best changing the cassette and chain. Putting a new chain on worn gears will result in slipping again.
