Giant claim 275lbs, or 120kg, for rider plus up to 10lbs for luggage/clothing so you're within their weight limit and should be fine. That's not bad going, I found a lot only guarantee road frames to 105kg which puts budget carbon beyond the reach of manly 19 stoners like us. Fortunately I'm not really into that sort of thing so has thankfully never made me cry.
I've never had issues with wheels, and wouldn't anticipate that you will if you're the same weight as me, unless you're a really unsympathetic rider.
Buy it, ride it, enjoy it.
