No, not a collaboration with the site. United teamed up with the actual brand Bicycle Union over in the U.K for this collaboration frame. There are no details on the specs, but it will be available in this pearl black and Rushmore red. The frame will be available in the U.K soon and worldwide shortly after that. Looks real good.

EDIT: Update
“So a few of you have been asking about frame specs, here they are-we went for classic geometry here, heres the brass!
