I’m selling a pair of used Zero Gravity OG-06 brakes, which I believe are the lightest model Zero Gravity has made. Included are used yellow Swiss Stop pads (used on aluminum rims). Also, I stripped a backing nut to one of the brakes and have substituted a steel backing nut. The steel backing nut is heavier by a few grams, and if the buyer is really concerned he could contact Zero Gravity. I’m sure they’d be able to provide another nut. Paypal accepted. $185 shipped to the buyer’s door, so long as the buyer’s address is in the US.
