I'm surprised no one said this ... You can use those cleaning kits with the box deal (forget what they're called :confused: ). Those are very good at cleaning the chain without having to take it off. I agree with
KleinMp99 about the chain tool, just get the CT-5 and take it with you, coz you might need it on a ride if your chain breaks. I own a Shimano IG90 and it doesn't come with a Powerlink deal like the SRAM chains do. I haven't had a problem with it (unlike my friend's SRAM chain which broke twice in the last month) ... maybe coz it's fairly new (3 months old). Funny thing is, my CT-5 saved our butts from having to walk back.
