Checking at 1800 miles on a commuter is smart since those miles add up fast in all kinds of weather. Also look at the chain rings and cassette, because a worn chain wears those down too and a new chain on old gears will skip. Keep a log of miles so you know when to check instead of guessing.

Thought the hype was silly till mine hit crack in 4 min flat.
