I had the same dilemma last season. I solved with retail therapy and purchased the 2017 Trek Silque SLR 6 (https://www.trekbikes.com/us/en_US/b...omens/p/17197/) and a 2017 Specialized Dolce Comp EVO (https://www.specialized.com/us/en/do...p-evo/p/107209). I love them both. The Silque is the smoothest road bike I have owned (it was my third carbon one). The Comp EVO is a fairly smooth ride and much faster than I expected. However, the wheels on the Specialized (same with my Amira) were slow to spin up so I upgraded the wheels. I can keep up and on a good day even lead the ride with my roadie friends. Both bikes are great and very versatile. But for the mixed riding you do, the adventure/gravel bike would be my choice mostly because I am OCD about the Silque.
Hope you can find something you love. Remember, the search for the right bike is part of the fun.
Enjoy,
Penny
