Hi I'm going to buy the Giant XTC 2 Composit are there any concern about this bike? I heard the 10.85kg for the weight of the bike but it's "long time ago". Are there anybody who checked the weight of this bike? If yes post the weight of the bike. Thank you for your attention, I just want a secure buy, like everybody here. I'm 169cm tall and 140lbs, what's the ideal size of bike? I just want to not rely too much on the dealer...
