is that one of those new invis-align chains? sweet!
(yes, i know you said you needed to add a chain, but when i was settin up my brakes and didn't have the cable hooked up, I just said that the braces company invis-align was making brake cables now and thats why you couldn't see it. nice conversion, cute cat, make sure he/she/it doesn't rub its face in the spokes when youre riding)
