So yesterday I took the Dolce out for a short ride. I took it home form the shop the same day so I could ride it a few times, then go back for a fitting. It rode well, fit well, but the derailleur was a little "slippy". I don't know if it's because it needs adjusting, or the Sora is really that much of a downgrade.

I also couldn't figure out why the Dolce was so much more comfortable than the Synapse when the measurements were so similar. I lined them up side by side and saw it: The seat on the Synapse was tilted up slightly, like I prefer it on my straight bar bike. With the drop bars, it caused my back to round, making the reach uncomfortable. I adjusted it, took it around the block, and now it feels really good, too
