I have a deposit in on a CAAD8, should be in within a few days. In the meantime the LBS had be take a Synapse Carbon 2 demo home with me. I like the ride of the Synapse and I like the ride of the R5000. Anything that you more experienced riders would do to point me in one direction or the other? Seems like the R5000 gets better componentry but the aluminum frame. The Synapse gets carbon but slightly lesser componentry. The Synapse is slightly more upright, but I could probabl match positioning on the CAAD.
