The only buffs I'd ever ride were the ones with the original ADARACING stems. The chromo ones are disgusting imo, too heavy. Plus aluminum buffs had a really clean, nice look that chromoly ones don't have.
I'm pretty sure fullcore protos are discontinued.
edit- does anyone know where i can get pink spoked protos? i'm like dying for a pair.
Spoked Protos are NOT going to break. So if you can pick between two extremely strong things, and one is lighter than the other, most people are going to pick the lighter one.
