Cyclo cross bikes are primarily designed for the sport of Cyclo cross. They have a relatively aggressive geometry, and extra features ( like secondary brake levers on the bars) not often found on Gravel / adventure bikes, which are essentially road bikes, which borrow certain ideas from CX bikes, like raised BB ground clearance, more steeply angled chain stays than commonly found on a road bike, better clearances for fatter tyres, and thru axles with disc brakes. CX bikes tend to be supplied with lower gearing than adventure bikes too.
