I need that front sprocket!! Then I'd be able to pedal on the highway at 55mph!!!!!! Craziness...

Thanks for the advice I was thinking along the line off this sprocket.

I should have said that I am making/trying to make a trike setup.

What about a mini moto sprocket?

Fredbert, where on earth did you come by that humungous chain ring? it's a total scream and I love it.
