Do you have to have THAT bike? Most of the shops I go to have at least a 30 day return policy if you don't like the bike and will give you a different one better suited to you. Not sure which model Synapse you have, and I'm not familiar with those bikes, but just a quick glance at the website and it looks like some models have an option of either a triple or a compact. Seems a lot easier to just switch out your bike than to switch (and charge you) for the components.....
