Is that kilometers or miles? Either way I think it is recommended to replace sprockets & chain as a set. Are the teeth worn or curved on the front or rear sprockets? Tight spot in the chain?
I actually went down one up front, 18T to a 17T. Did not replace the chain, sprockets & chain appeared OK and had about 12,000 miles of use. Figured I would be replacing chain & sprockets sometime around or soon after the 24000 mile service. Have ~23000 miles on the clock now.
