Pards, you're probably asking the wrong forum. Kung taga-Pinas ka, you probably need to go here (www.pinoymtbiker.org/ Sorry Francis! ). =P
Pero if you're looking for Mosso or any cheap frame from China, punta ka sa Quiapo (I forget which street but it's just right next to the pedestrian overpass). There are several bike shops there selling these frames.
