Disappointed in REI's saddle substitution
I am disappointed not so much in Cannondale as in REI. REI's specifications differ from the Cannondale specs published online. For example, REI provides a Fizik Aliante Delta saddle but Cannondale specs an Aliante R5. The difference is significant because accessing the angle adjustment screw on the seat post requires a saddle with a center hole, but the cheap REI spec saddle is a solid saddle. That means I need to remove the saddle to adjust the seat angle. (There is a plastic nut (add?) that might be for adjustment, but it does not budge without removing the saddle.) REI should highlight its changes so that co-op members are fully aware that they are buying a product that is different from the manufacturer's standard specification. Apparently, I should have gone line-by-line to compare what Cannondale describes and what REI describes. If that is the expectation, REI should list the product as a "Modified Cannondale Synapse 1" rather than a genuine Synapse 1 as sold by Cannondale.
Saddle adjustment on synapse 1
You need to look closer , there is a star nut with a set screw so you can move it if needed to stay within the range. All you have to do is turn the star style nut from the front to tilt the saddle. Simple and ingenious.
