So a fair assessment would be connected to mountain bikes, imho.

Take a Fantom 29 w/ disc and put it through the same single-trail attack you would say a Cannondale F4, or even Hardrock 29 disc. Have a solid mountain biker make 3 passes with each, and get his feedback.

I digress, it would be very interesting to see a BD.com bike put up against a boutique bike, but I don't think it would happen.

On the aside: I know the owner of bd.com was a regular contributor here for a long time, if he was still around maybe he could weigh in on his product?
