It's basic math, but with a bunch of variables. Gates system can save 10 ounces or more over a timing chain setup. But as Ritterview showed, with the lightest available 10 speed chain, and very light timing rings, the difference gets much smaller.
So it depends on what chain/rings you're comparing it to.
From a previous post:
"Gates sync belt ring. 95 grams X 2 = 190 grams
Gates carbon drive belt 105 grams
Total weight of the Gates system = 295 grams
42 tooth Hegoa Chain ring. 35 grams X 2 = 70 grams
Campy Record 11 chain 337 grams
Total weight of chain drive system = 407 grams
407 - 295 = 112 grams or 3.95 ounces."
