Which chain do you guys recommend I purchase? 2005 XT225. ~8,000 miles on the bike. I see a large disparity between chain prices, from $60-$140 for an O ring type chain. If I go cheap will I regret it? I've only owned the bike for 2 weeks but the current chain looks a bit rugged and has a tiny bit of extension/compression, so I want a backup ready. Thanks for the advice in advance!
