THE PRIMO BALANCE RIM IS SUPER LITE YET WITH IT'S OFFSET SPOKE HOLES SHOULD STILL KEEP THE STRENGHT OF MANY RIMS THAT WEIGH MORE. CHECK THE TOP SIDE OF THE RIM AND SEE HOW PRIMO HAS DRILLED AWAY MANY OF THE EXTRA METAL THAT DOES NOTHING BUT ADD WEIGHT. NOW PRIMO HAS IMPROVED ON THE REGULAR BALANCE RIM BY MAKING THEM OUT OF 7000 SERIES ALUMINUM. PRIMO CLAIMS THAT THIS MAKES THEM EVEN LIGHTER YET STRONGER. PRICE IS FOR ONE RIM. WEIGHT = 15.8 oz.
