    What Single Speed Frame is this?

    What Single Speed Frame is this? Its setup so it can be a single speed or a multi-speed bike (front and rear derailluer) bike bike?
    I think it might be a Kona, but I was told it is a Redline??

    Looks like an old Soma Analog.

    But not everything quite matches from the Soma photos. The dropouts look like the Soma IRD/Tange ones though.

    For what wheel size was that bike designed?

    Most SS-able bikes have derailer hangers too, so that does not narrow down much.

    I would focus on the shape of that DT/HT gussett.

    Kinda looks like a Redline Monocog.

    Contact Redline with the serial number to confirm.

    I could be wrong but I don't recall ever seeing a Monocog with the sliders like that, they typically all have horizontal track ends.

    The Monocog Flite had sliders. Probably IRD.

    I think those open loops on the rear dropouts would be pretty recognizable to anyone who had seen them before, but I don't recognize them.

    Pretty sure it's not a Kona. It could easily be a custom frame.

    Can you post a pic of the serial number on the bottom of the BB shell?
    Rigid SS 29er
    SS 29+
    Fat Lefty
    SS cyclocross
    Full Sus 29er (Yuck)

    Stop asking how much it weighs and just go ride it.

    Its a 27.5 rear at least. The Gussett looks like a Kona but it also looks like copy of a Bontrager gusset.

    Isn't a Kona Explosif a light frame? At least light for a Steel frame?

    It isn't a monocog flight. I don't think Kona makes dropouts like that, especially during the era of 1 1/8th headtubes.

    I don't think the B-Side or Redline ever used a gussett like that. IRD sliders and that open gusset... Are those shift cable guides on the downtube?

    Do we know the wheel size? Is it a 26er?

    This leads me to think it could be custom.

    It has shift cable guides on down tube and shifter cable routing guide under the bottom bracket.

    PVD has similar slider dropouts on some of his builds, he is on this forum as well, perhaps give him a ping with some pictures?
    I would guess though, if it is one of his, it is an older version as he is doing some very interesting geometry things at the moment. Either way, I think you scored a very cool frame.
