not convinced - just cause a cross bike has heritage it doesnt mean it doesnt fall into the hybrid class of bikes. A hybrid doesnt just have to be a flatbar roadie/mtb. butif it makes you feel better call it whatever you want.
Quite funny when you think about it.
Bike manufacturers and their marketing departments create a Hybrid bike not realising they'd been producing them for decades, even before they'd created the other half of the Hybrid form.
