    This frame weighs only 5lbs.

    I bought this frame today was surprised at how light weight and well built this frame is. I'm not sure who makes this frame because previous owner got this in a storage locker he bought at auction. Paid only $50. Going to use this frame on a new build.

    Custom Bike frame

    Wanted to post this on here since I haven't been getting much interest on other sites.

The back wheel...
