Limited internet sleuthing shows that Blackcomb is a rebadge unique to the Philippines, looks like they use stuff from Kent International, makers of stuff like the GMC Denali BSOs. A bike shop in Cebu City called Cebu Kentbike has a bunch of different road and mountain Blackcomb bikes, leading me to assume the OP is from the Philippines.

Again, no idea what the exchange rates are, but similar Kent stuff here in the US would be sub-$300USD. I can't find more than one pic of the road bike, and it's too low-res to even see what componentry is fitted... but the chainrings look riveted.
