giant advanced BB

[Doyleyburger]

Been toying with the purchase of a Giant TCR Advanced 2 but prefer the colour of the advanced 3. The advanced 3 is a tiagra groupset which isn't a problem as I have an 11 speed 105 groupset here which I can put on the bike......all except the crankset. The specs say that the tiagra chainset is a shimano press fit, so I was wondering whether it would be a straight swap with a 105 once I buy one. Never heard of a tiagra chainset being press fit before now.
Can any of you fine giant owners confirm this ?
Thanks

The Shimano press fit BB is for all hollow tech 2 cranks, so the 105 will be a straight swap......
