So, this weekend I have seen and ridden Ruby Elite Disk and base Diverge (without future shock). I am stuck, as I have not yet seen 2018 Cannondale Synapse in any modification. None of the stores around have them on display and I am very interested in this bike, as they are the most affordable with the same components. For instance, Synapse disk Tiagra is $500 cheaper than comparable Domane ALR 4 and $300 cheaper than Diverge. For the price of Domane with Tiagra you get Synapse with 105. There is a $500 difference between Cannondale 105 and similarly built Diverge.
I am at loss to understand the price policy and why Cannondale bikes are so much cheaper.
