Good point. I replaced my OEM chain last fall with the closest equivalent riveted EK 630 chain, and new sprockets I could source. I have about 2-3K miles on the new chain and aftermarket sprockets, and have as yet needed to adjust the chain to take up excessive slack. I also repack the sprocket bearing whenever I mess with the rear wheel. I actually remove it, clean it out, then repack it like I would an automotive wheel bearing.
Perhaps the sprocket bearing has left the area?
I bought aftermarket sprockets, against better judgement, but they seem to be ok so far.
I shopped around a LOT before I bought this chain. My dealer had some really CHEAP chain that they wanted 3 times more than I paid for this high quality OEM type o-ring chain. Special note.. be careful counting those chain links. I counted mine 3 times, and the old chain / sprockets were binding up so bad that I could not turn the rear wheel smooth enough that I kept losing count and ended up ordering in the wrong chain (too short) by 2 links. I even marked the starting and end points and STILL screwed up the counts. Every time I had to grunt turning that rear wheel, I must have started back to counting 2 links from where I ended at. <sigh>
AND I bought the elcheapo chain riveter that needed only a little bit of practice and ANOTHER EK master link after screwing up the original one.
Riveting the chain definitely took another try to get it right.
