Hi, I have small question. I need bike for long distance >500km, now I have old Jamis Xenith with Dura 7900. I can chose one bike from title of this post:

BMC SLR01 Ultegra Di2


LOOK 675 light Ultegra mech

What it will be better? Price is the same. I can't try any of this two before buy, but frame size will be correct.

Thanks for any adwise
