The Panaracer GravelKing Slick 27.5x1.50 / 650x38B bicycle tire is designed for pavement, hardpack gravel, and all-road riding, combining a nearly slick center tread that favors speed while preserving gravel-capable casing support.

The GravelKing Slick uses Panaracer's ZSG Gravel compound, TuffTex casing, and BeadLock construction. Its fine tread minimizes rolling resistance on firm surfaces, making it a practical choice for riders who spend most of their time on pavement and compact gravel. This variant is tubeless ready for use with a compatible rim, sealant, and valve.

Key Features

• Fast center tread: A fine, nearly slick pattern supports efficient rolling on pavement and hardpack.
• TuffTex casing: The reinforced casing balances ride feel with protection for mixed-surface use.
• BeadLock construction: The bead profile is designed for consistent mounting on compatible rims.

Benefits

• Carries speed efficiently on road-heavy routes without giving up all-road versatility.
• The casing supports everyday gravel use while maintaining a responsive ride.
• The exact size and construction details simplify wheel and rim compatibility checks.

Best For

• All-road rides, urban routes, bike paths, and compact gravel.
• Riders who encounter mostly firm surfaces and do not need deep, widely spaced knobs.
