Specialized has introduced its latest innovation in mountain bike tyres: the Grid Gravity Radial series, featuring the Butcher and Eliminator models. These tyres are engineered to enhance grip and compliance, particularly for riders navigating natural, technical terrains.
Innovative Radial Casing Design
The standout feature of the Grid Gravity Radial tyres is their ‘Sweet Spot Ply’ construction. By adjusting the casing thread angle to approximately 70 degrees—a significant increase from the traditional 45–50 degrees—Specialized has achieved a 30% reduction in radial stiffness. This modification allows the tyre to better conform to uneven trail surfaces, resulting in improved traction and vibration damping. Notably, lateral stiffness decreases by only 7%, ensuring that cornering support and steering precision remain uncompromised. (bikeradar.com)
Enhanced Contact Patch and Grip
The refined casing design increases the tyre’s contact patch by about 30%, translating to a more supple and predictable ride feel. Riders can maintain their usual tyre pressures while experiencing greater traction and comfort on rough, technical trails. (bikeradar.com)
Model Specifications and Pricing
The Grid Gravity Radial tyres are available in two models:
-
Butcher Grid Gravity Radial T9 TLR: Designed for front-wheel use, this tyre features a T9 rubber compound and is available in 29” and 27.5” x 2.4” sizes. The 29” version weighs approximately 1,330g. (bikeradar.com)
-
Eliminator Grid Gravity Radial T7/T9 TLR: Intended for rear-wheel use, this tyre combines T7 rubber in the centre with T9 rubber on the edges, also offered in 29” and 27.5” x 2.4” sizes. The 29” model weighs around 1,330g. (bikeradar.com)
Both models are priced at $90 per tyre. (bikeradar.com)
Target Audience and Usage
Specialized has tailored these tyres for trail riders seeking maximum grip and terrain feedback. However, riders focused on bike-park laps, downhill racing, or those preferring a firmer, high-impact supported feel may still favour the standard Grid Gravity casing. (bikeradar.com)
With the introduction of the Grid Gravity Radial series, Specialized aims to provide a tyre that offers a smoother, more controlled, and grippy experience without necessitating changes to riders’ existing bike setups.
