    bike is equipped with a tiagra groupset, crankset is too big, 30/40/50 teeth.
    so just put a 22/32/42 deore crankset on.
    in the bikestand it all seems fine.

    will it be ok?

    I’ve done it – fitted a 2x MTB chainset on a CX bike for the same reason. Chainline will be a couple of mm out, so you may have trouble with it running smooth on small sprockets / chainrings. Likewise, if using a road front mech, it might not have enough ‘swing’ to cope with the big ring.
