Im 99.9% certain the Cretin will only be available as a complete bike, priced at $499 w/ a carbon I803 fork. The tubing is roundish but the top tube has a bit of a flat, more squared-off profile. It's a really cool frame. For those who don't know, it's named the Cretin to give props to a local San Diego bike crew (The Cretins).

I'm hearing there are future plans to make more 721 frames at some point in 2015 but I'm not quite sure when that will happen.

Another new complete bike Leader will be offering soon is the Cure, which is also a really cool bike with a good back story.
