The Specialized Fast Trak GridLite XC Tire is optimized for cross-country racing with enhanced traction across all conditions. The newly revamped tread design reduces weight by up to 80g, improving speed and efficiency. Featuring precise shoulder knob spacing, it sheds an additional 40g while providing better grip on loose terrain. The signature Fast Trak knobs return with a lower profile for faster rolling resistance. All XC models now utilize the T5/T7 Dual Compound for optimal grip and durability, while the S-Works casing has been discontinued. The GridLite all-purpose trail casing offers reinforced sidewall protection for rugged trails.
