How can tire sealants be designed to balance the need for effective puncture protection with the demands of high-speed gravel riding, where heat buildup and tire flex can compromise sealant performance, and what innovative materials or formulations might be explored to achieve this balance? What role could advancements in tire sealant technology play in enabling riders to push the limits of gravel riding, and how might these advancements intersect with emerging trends in tire design and wheel technology? Are there opportunities for tire sealant manufacturers to collaborate with frame and wheel builders to develop integrated systems that optimize sealant performance and overall ride quality?
