• I don't have one, but I would say: a tenner.

    I have spare spokes though, I use them for stirring paint, etc.

    Anyway: nothing wrong with the front wheels. Nothing good either, except for the funny looks and corrosion resistant spokes.
    The rear wheel is a different story. The freewheel and bearings need some maintenance (cleaning, lube).

    Keep checking the spoke tension.
    Usually a bit too low.
    But be careful that you don't overtighten them. Especially the black FIR rims may devellop small cracks. And they're out of production.
