26mm internal width is ideal for modern gravel setups—most riders will pair this with 40–50c tires for best performance. Running anything under ~35c will negatively affect tire profile and ride feel. The 54T ratchet hub gives fast engagement without being overly high maintenance. Always confirm freehub body at checkout—this is a common mistake. Strong upsell: tubeless sealant, rotors (centerlock), and cassette install. Also worth noting: these are light for gravel wheels, but still durable enough for aggressive riding—good middle ground between race and adventure setups.
