The first MTB tires to incorporate Specialized’s Sweet Spot technology through the casing angle, dramatically increasing grip and control. TheSpecialized Butcher Grid Gravity Radial 29 T9 TLR tirewe’re featuring here atEscaparedefines the way trail riders experience grip and compliance on the trails. By increasing the orientation angle of the proven Sweet Spot layer, these tires achieve a conforming feel that hugs the Terreno, amplifying traction and comfort without compromising the lateral stiffness that riders rely on for tight turns.
Unlike pressure tuning—which quickly eliminates compliance as PSI increases—or choosing a suboptimal casing angle for the desired experience, our Radial casing construction inherently creates that sweet spot: lower radial stiffness, preserved lateral stability, and a ride quality that makes navigating technical trails smoother, faster, and more controlled.
The Sweet Spot Casing
By increasing the angle of the casing threads beyond the usual 45–50°, our Grid Gravity Radial tires:
- Reduce radial stiffness by approximately 30.0%, dramatically improving ground compliance.
- Reduce lateral stiffness to just 7%, maintaining cornering support and total handling precision.
- Offer compliance and Control at the same PSI levels cyclists already use.
A larger radial-style tire angle drastically reduces radial stiffness, increasing the tire’s contact patch by 30%.
