Not awful - IMO same quality as 8-speed Sora (but not on par with newer 9-speed Sora). However, it is worth noting that 8-speed drivetrains are virtually obsolete. Modern road bikes almost all feature 9 or 10 speed drivetrains. It's not that the extra cog is really that much better; it's simply that running a 9 or 10 speed drivetrain opens up your options for replacement parts or compatible upgrades.

That said, I would consider canceling the order and maybe looking to see if you can get a on sale or used 9/10 speed road bike. The OCR2 or OCR1 is one to consider; if you can find a last year's model you may not have to pay too much. Looks like you already know your size, so it shouldn't be too hard. It's worth it in my opinion, as my first bike was 2200 as well and I ended up selling it within 3 months for a 9-speed bike. Of course, this may have come from Bikeforums envy, but I don't regret it.

Let us know how it turns out.
