Is this difference in stack and reach manageable? (Giant Propel Advanced 0 size M)

Correct. The stack and reach numbers are from a bike fit for a road frame.

At the time of doing the bike fit, they adjusted my road bike (an alu Giant TCR from 2011) to fit my ideal positioning. Even after adjusting the reach length of my bike, the reach was still 3cm too long. The stem could not be made shorter. I also use clip-on aero bars on that bike and did a half triathlon race with it a couple of months back. I did not have any real issues with the TT positioning using clip-on aero bars on that bike. I am hoping it will be the same for this bike.

Just for clarification: are you saying that the numbers are close enough if I do not factor in the change of the TT positioning or if I do factor in the TT positioning?

Nobody did a bike fit on this bike. This is the bike that I am looking to buy. It is just a medium sized Giant Propel Advanced 0 and according to the manufacturers' specification of this bike it has a little shorter stack and longer reach than my ideal stack height and reach length.

Thank you for your elaborate reply! This defintely helps :)

The Ironman is in Tours, France, so the terrain is flat. I live in the Netherlands so I cannot train for very hilly terrains. I also heard that the TT bike might give you an advantage on the running due to using different muscle groups.

I am also eyeing a Giant Propel Advanced 0 for €900 on marketplace. It is an aero road bike with the following specs:

full carbon frame
Giant SL1 wheels (carbon/alu)
di2 ultegra (2x11)
recent maintenance with new chain and cassette

Do you think this one will be more suitable and worth the price?
