Chains and sprockets replacement

[thorns]

Just about to replace my chain as its adjusted as far as it can go.
The sprockets look to be okay and in pretty good condition, but would you usually swap them out for fresh ones when you change chains?
I have a spare front and rear, so happy to change if its good practice.

I always do chain and sprockets as a set.

a few will say you dont need to bother, but a partly worn sprocket will wear a new chain quicker, and vice versa.

do them both.

do them both. front sprocket is way smaller and usually wears twice as fast as the rear, that'll give you an indication on when it needs replacing first.
