I had considered the frame only option from BD but the wheels, stem, seatpost, saddle, handle bars, bartape, tires, tubes, etc all start to add up and it made more sense just buy a complete bike for $1600 vs $1000 for the frame. And of course, if I rode it even a little, I would say that it was used.
I'm just curious what kind if hit Rival groups take on the market if they're sold as new take offs or slightly used.
