I've had my Hope Bulb in QR and 12mm TA modes, both using adapters for the frame. The QR ones fit into the dropout plugs and have a narrowed end for a QR, and the 12mm are like giant thick washers/plugs almost. I just had it apart............LOL
Email Intense if this is confusing. I am 100% sure there are QR and 12mm adapters you used on this frame. I guess you could get away with using no adapters but I dunno why you would want to, the adapters fit in the grooves in the dropouts like money.
