Is the DA cassette worth it?
I know the differences regarding weight (50ish grams), material (some TI cogs), and price.
How much faster does the DA cassette wear out? Is it worth it for a race-day wheelset? What if (hypothetically) the price difference was around $45?
EDIT: Yes its 545am in my time zone and yes i'm on bikeforums. I LOVE waking up early for races.
