Dunlop Enters the MTB Tire Market With Geomax Tire Range Launched at Sea Otter

Dunlop has officially entered the mountain bike tyre market with the launch of its Geomax range at the Sea Otter Classic event held at Laguna Seca Raceway. While Dunlop is a household name in motocross and supercross tyres, this marks the brand’s return to cycling after its founder, John Dunlop, originally developed the first practical pneumatic tyre for a tricycle in the late 19th century. The new Geomax MB tyres leverage Dunlop’s extensive experience in off-road motorcycling, applying motocross design principles and rubber compounds to mountain biking for the first time. The Geomax MB range is divided into two main lines, each offering front- and rear-specific tyres designed for different riding styles and terrain. The MB34 series is aimed at aggressive riders seeking maximum traction and control on technical, loose terrain, featuring tall, sharp tread lugs and robust casings suitable for downhill or enduro use. In contrast, the MB53 line focuses more on rolling efficiency and speed, catering to riders prioritising smoother, faster rides. Both lines incorporate Dunlop’s advanced casing technologies to balance durability, support, and weight. Particular attention has been given to the front and rear tyres’ tread patterns, which are distinctly tailored to their roles. The MB34F front tyre emphasises precise handling and mid-corner stability with a rounded profile and a combination of soft-touch hex blocks and split blocks designed to absorb impact and maintain braking stability. The MB34R rear tyre prioritises traction and braking control with large, rectangular centre knobs and multiple biting edges using Dunlop’s Progressive Cornering Block Technology (PCBT) to enhance grip during acceleration and cornering. Pricing for the Geomax MB34 Downhill casing tyres starts at around £110, with sizes available in 27.5 and 29 inches and widths of 2.4 and 2.6 inches. Weights vary depending on size and casing, with the 29” x 2.6” front tyre weighing approximately 1,425 grams. Dunlop’s entry into the mountain bike tyre market signals a significant move, potentially shaking up the sector by introducing motocross-derived technology and design expertise to mountain bikers seeking high-performance tyres for demanding conditions. Further developments and expansions of the Geomax line are anticipated as the brand establishes itself in this competitive field.
