Ihave a secula and a lumatec IQ. However the secula is mudguard mount and the Lumatec would have to be a bodge. as the the bit of plastic that houses the bolt has gone on its holidays. You can have them for free tho.
bodge could work, mudguard is good. Do you mean the bottom of the plastic housing? I think I bodged a similarly broken IQ with a pipe clip for a while. Anyway I'll PM.
I need some lights for the winter fixeh. Anyone selling a secula and a mediocre front light?
