The WTB Trail Boss 2.25 29" and Vigilante 2.3 26" mountain bike tires complement each other well as a bundle for riding on various terrains and conditions. The Trail Boss has tightly spaced, blocky tread that minimizes rolling resistance on smooth hardpack while providing excellent braking grip and traction when needed. It has supportive side knobs to maintain stability on off-camber surfaces. Weighing 938 grams with a durable casing, the 29" Trail Boss works well as a rear tire for enduro and also excels as a front tire on less technical trails. Meanwhile, the 26" Vigilante features open, square blocks that aggressively grip loose, wet, muddy, and rocky terrain. Weir approved, this 914 gram tire delivers faster rolling speed than expected for the amount of traction it provides. With two tire options specialized for different ride styles and conditions, this bundle allows riders to equip their bikes for optimized performance on any trail.
