The Force costs more, weights a lot more, is less reliable, with inferior braking and shifting quality. Other than that, it’s good
I ended up buying a 2019 Madone SLR (rim brake, DA Di2) after testing it against the Venge. The Venge is a bit more lively but rides super harsh, and feels less compliant. Both bikes hold speed really well. On looks alone the Madone wins hands down. Other than having to clean my bottom bracket couple of times due to riding in rainy muddy waters, I’ve had zero issues with the bb90. Love the Madone!
