• I have a front wheel with (I think, it's destickered now) one of these rims (Rigida Zac 2000 'Dsic',

    Some sellers seem to suggest this is a disc only rim, others say it can be used with a rim brake.

    The cross section doesn't look much different to (Rigida Zac 2000),

    So, other than that the braking surface on my rim being painted and not machined, any reason why using a rim brake with it is going to send me to a fiery death?

    I understand the finish will deteriorate as I brake on it. In the long run I'd like to change to a black rim with a machined silver braking surface (Mavic A119 or something) but it would maybe be handy if I could use it with a rim brake for the time being.

  • I’ve used the Mavic Xm319&119 (disc) rims with rim brakes and it was fine. I did it because the rim looked identical to the A series that has machined side walls. I think it’s the same rim, with and without a machined side, and either way, those zac rims are pretty overbuilt so there’s plenty of material.

    I would reconsider if it was a lightweight rim like pacentis, but I would really not worry about using a rim brake on the zac rims.
