Almost all gravel bicycle wheelsets will be disc brake specific, tubeless-ready, and spin around thru-axles. The internal rim diameter will be somewhere between road wheels and MTB wheels, typically in the range of 20-25mm, to accommodate wider gravel tires. Gravel racers and bike packers will have different demands in terms of wheel weight and durability too, but we’ll touch on that a bit later.
