DerferMark replied to Elwood Gruschow's discussion Stainless steel chains
"Look better and slightly easier to clean but I don't think SS chains give you extra chain life.  But you're right, the cost difference isn't that much.  I generally replace my chains every 3000 mi. or so but results vary."

"That's a whole math problem in itself, figuring out the shortest possible route (ie. repeating as few lines as possible)  I just traced it out manually on Ride with GPS and audio cues told me when to turn as I rode it.  I'm sure…"

"Wow.  Sooo, how do you pre-map the shortest route for a celtic knot? First track working toward the center and then finishing working outward, or.... ? That's really well done. "
