Chain maintenance products

[Velobambina]

Velo-b, I've been curious about Purple Extreme and have considered giving it a try when I run out of my bottle of Rock'n'Roll. What else have you used that you'd compare it to?

I found that it's cleaner, probably because you use less. Since I'm a distance rider, I need something w/a lot of staying power. Purple Extreme lives up to its promise of 400 miles per application (of course, could be a bit less if the weather is rainy).

I've used ProLink, which is fine; Pedro's Ice Wax (found it was a dirt magnet but I might not have been wiping it off the chain good enough); and Road Rage.
