Found a difference between the Boreas and the Giant TCR today. Up till now I have thought the two frames virtually the same to ride, but I have been trying to calm down the TCR as it seems a little skittish. It seems to follow the little variations on the road and hit a manhole cover and it bounces a bit. Cured it somewhat by running the Ultegra wheels at a lower pressure than I normally would but still have to think about riding more than on the Boreas.
That was till today. I have hills in my area and if I was to asked a choice between the two bikes for hill climbing ability- it would be difficult as they are very close. But if I had to give an answer it would be the TCR. Don't know why but it just seems to be easier to pedal up the hills.
Now today- I went out for a short ride and went down a 16% hill. I am used to speed so I just went for it. This hill has a curve halfway down it and today- I had to fight the bike round the curve. Didn't brake but in hindsight- it could have been messy hitting the bank. Have to admit that I went for it and managed to break 50 mph on a road bike for the first time. Boreas has got to 48 but today was the fastest I have ever gone on a road bike.-But that TCR was hard to controll round that curve. Boreas just does not move out of line or even feel unsafe at speed.
So It looks like I still have some work to do on the TCR. And Although I am not unhappy with the bike- I am wondering if C.F. suits my riding style and ability.
