thanks guys,
Carleton i know the diference, meaby i dont wrote correctly.
Godsight thanks for the info. you are comparing top disc vs chinese rims.
but what if you use a wheel more lighter than a disc?
for example
rear mavic comet 980g. (the best in the market) shop.mavic.com/en-int/comete-track-rr0719.html
vs.
rear mavic cosmic ultimate 40mm deep, 695g. shop.mavic.com/en-int/cosmic-ultimate-rr0819.html
almost 300g! you feel that in aceleration
