Have you considered the Trek Domane ALR 4 ?


It's got slightly more relaxed/upright geomentry, and has the Tiagra groupset.
Which you may or may not be interested in.


I've been looking all over for a 2017 in a 58cm size, and cannot find one.
One of the LBS here has a 2017 58 cm Trek Domane ALR4 in it's rental fleet, and I plan to rent it for a day this fall, to see how I like it. The shop tells me it's been lightly rented (because of it's size), but they don't want to sell it.


Don't know if renting is an option for you. I also may have to end up going with a 2018 in the spring.


Good luck with your decision.
