I purchased my Ruby in March. The shop was willing to order one in my size to try and knew I might choose not to buy it, but said they would be able to sell it because it was early in the season. If you can't try the right size now, see if you can get your LBS to do this.
The other bike shops did not offer to do this, and I road-tested a 48 cm Cannondale Super Six, knowing it was too much of a stretch, but did not even try a Cannondale Synapse. I also tested a Trek 47 cm and it was also too big for me. The one shop really won me over by ordering the bike w/ no commitment to buy.
