The Ground Control T5/T7 tire is built for XC and trail riders who want speed without sacrificing grip. The fast-rolling T5 center boosts efficiency and tread life, while grippy T7 shoulders deliver confident cornering and braking. Previously you had to choose between full T5 speed or full T7 traction—now you get both. It’s race-ready performance with trail confidence in one tire. Recommended Pairing: Trail Control Grid Lite T7 front / Ground Control Grid Lite T5/T7 rear: Fast rolling and control. Grid Lite T9 front / Grid Trail T7 rear: Grip and durability for aggressive riding.
