Anything that I have bought above Tiagra level would have been an opportunistic bargain and for some reason not as many bargains turn up in 105 form. I have only bought Ultegra because it was cheaper than the 105!
I love the higher quality of my 105 hubs but they probably will not last any longer than the Tiagras.
In comparison the 105 rear derailleur doesnt strike me as different quality level to the Tiagra one.
If you could spare another few minutes could you check the other bits of kit on that bike below and give me your opinon

I wanted a cannondale caadx 105 2016 but they seem to be unattainable and the 2017 is just out of budget which had me thinking of getting a sora but now ive found other bikes and there above a ultega bike for under 1000
A lot of the componentry there is outside of my direct experience. The only deficiency that struck me for the Tiagra model was that it had BB5 brakes instead of BB7s and the one is far better than the other because it has two adjustable pads rather than just the one moving pad.
However they contradict themselves about whether the Ultegra has BB7s or not.
If it does then I would opt for the Ultegra version and enjoy the added quality of Ultegra.
If BB7s were available on the Tiagra as an upgrade I would save a bit money and have that. I think that 10 speed may be more practical and cheaper for running costs.
Another point to check, if you are going to be doing hilly rides is "is the gearing low enough"?
Which could swing me firmly into the Tiagra bike as it can be retro fitted with a large rear cassette and an MTB derailleur, which I doubt the Ultegra can.
