It looks pretty cool, but I don't like the eccentric axle (some others do). I can make a cooler one than that for about 1/2 that price, if you can wait a couple of months for me to catch up on some of my other projects.
You have to remember that mods like this are for purely astetic purposes, it won't make you bike handle any better. However, neither will custom paint, etc., & we all lust after that. I like anything that tends to individualize a bike. And, foggy, you can do anything, it's just time & money.
