No. 303S are 1558g before sealant and heavier tires while D45 Disc are 1420g. 303S are 45mm deep front and back while the D45 is 46mm front and 54mm back. Zipp 303S are normally $1400 but sometimes you can find for $1300. D45 are $1300 but they always have a 10% coupon, free shipping, and don't have sales tax nor are most people charged import tax so the true cost is more like $1170
