I am I know it lol but that’s how I have fun and learn. I’m trying to shave some weight. I’ve ordered some solid tires. That I plan to fit on some 70mm deep dish wheels I got for $40. So that’s going to add some weight. It’s a good thing my Electra super delux frame is aluminum. Anyway so I hit google with “lightweight bicycle chains” and read on another forum *i don’t think I can post url’s yet* that 7,8 and 9 speed chains work blah blah. Then went to kmc dot com looked around. Saw inner and outer chamfering? Called kmc today. Didn’t get answer from them either but I did notice after looking further at kmc dot com how the few bmx,track or fixie chains that come chamfered come with inner plate chamfering so yea...
