No, but I am sure they would be useful as long as they aren't crazy expensive. Would they make the chain wear differently from being made out of a harder metal?

My sprockets made out of paper mache. It's so light my bike power wheelies in seventh.

I hate you guys. With the exception of T-rock not one person actually attempted to answer my question. I never said I was getting them for the weight I said I wanted any first hand experience on if they really last like their suppose to so that would be one less thing to maintain throughout the year.:dthumb:

OSP had a pretty straightforward answer. I thought you were addressing weight somewhat also.

Pretty durable too? I might look at fabbin one up if I get a chance.

hey fucker... I did too... I said check with Tigger... I thinkn he's runn'n one

He probably has your bitch ass on ignore. I know I did for a while. Not like you contribute anything intelligent to the forum.

He's better than contributing to the ghey factor of the board like you.

Well then its a good thing i'm not a homo.

Dude shit yeah. This japanese guy that made it for me made it look like a swan in the middle and it only has to be rebuilt every couple miles.
It's JDM AND lightweight.
