Just a WAG here coming from my experience with Cdale, my guess is the Synapse is a heavier frame. This is not bad in any way, just different. Add the light, radar, and the battery to power them, the weight difference may well be defined.
Frankly, my choice is always to go local as the local shop and employees spend their money in the micro economy in my neighborhood, and thus pay local taxes in my neighborhood, both of which benefit me and my family and my friends. The warehouse three states away does nothing to support my community.
