  • How far off flat is acceptable on a brand new unlaced rim?

    Depends how stiff it is. I'd take 5mm on a 36H CX18, because it wouldn't take much to pull it straight. Something wide and heavy and with a low spoke count should be within 1mm because otherwise the spoke tension will be unacceptably uneven once the rim is straightened out.
