Flat steering angle, long wheelbase and plenty of fork travel for a smooth
straight-line stability. Low bottom bracket for better road holding
Wide range depending on the gravel bike model, but tends to be more upright and suitable for long distances
Wide range from 32 to over 50 millimetres wide and different profiles from road to mud. Some smaller wheels (27.5 inch) for even wider tyres. Usually tubeless tyres.
Wide gear range and suitable for beginners with significant reduction in the mountain gears on gravel bikes. Chainrings with large jumps, usually 48/32 or 46/30. For single drivetrains, wide-range cassettes with large gear jumps
Brake disc diameters of 160 millimetres are standard at the front and rear, and in some cases 180 millimetres at the front wheel.
Relatively wide and often flared at the ends for better off-road control on gravel bikes
Many mounting and transport options for luggage, water bottles, tools or mudguards
Steeper angles and the shortest possible wheelbase for very manoeuvrable steering behaviour - this allows foot contact with the front wheel. Comparatively high bottom bracket so that the chainring does not touch down on obstacles and you can pedal through bends
Stretched riding position in contrast to a gravel bike with a lot of weight on the front wheel
Limited by UCI regulations to 28 inches with a width of 33 millimetres. Different profiles for dry to muddy surfaces. Tubular tyres from special suppliers are often glued on, but the proportion of tubeless tyres is increasing
Small jumps, little bandwidth. Typical gradation with two chainrings 46/36 with (deliberately) many overlaps, sometimes also single chainrings with a narrowly stepped road bike cassette
140-millimetre discs are usually sufficient for the requirements on the short circuits
Rather narrow and classically shaped for more manoeuvrability on narrow courses
Often only one bottle cage can be fitted, but the top tube is specially shaped so that the bike can be shouldered better in running sections
