Unknown has been on a roll lately dropping some dope new stuff left and right. Hot off the release of the PS1 comes this new beaut complete with a tapered 1″ headtube. The SL1 will be out next month and judging by how solid it looks should be seen rolling the streets not long after. Dig that seafoam on the prototype here but I’m sure the matte black and high polish on the production frames will look just as good. More here!
