Panaracer launched its first GravelKing tire ten years ago, before gravel was really a thing in most riders' minds. Since then Panaracer has added more and more GravelKing variants to keep pace with the explosion and diversification of drop bar off-road riding and maintain its presence in the best gravel tire ratings. The new X1, X1R, and X1+ are totally new tires though and a summer of riding in all conditions on solo and tandem bikes has proved they’re excellent performers at a good price.
