The Romet Mustang M8 embodies the excellence of the modern XC/Marathon hardtail, designed and manufactured in Poland by one of the historic leaders of European cycling. Combining lightweight (13.5 kg), optimal stiffness and top-tier Shimano components, this 29-inch MTB is aimed at demanding riders seeking performance, reliability and comfort on challenging courses as well as long marathon rides.

Technical Overview

Built around a 6061 X-Lite aluminum frame using internal hydroforming and full cable integration, the Mustang M8 is based on an XC marathon-oriented geometry with a 70° head angle ensuring stability and precision. The Rock Shox Judy Silver TK RL fork with Solo Air cartridge and 100 mm of travel offers a perfect balance between pedaling efficiency (lockout available) and shock absorption. The frame adopts the Boost standards (15x110 mm front / 12x148 mm rear) and Centerlock disc mounting, guarantees of lateral stiffness and maintenance simplicity.

Shimano 1x12 Drivetrain and Braking

• Shimano Deore/SLX Groupset: The modern 1x12 single-chainring drivetrain combines simplicity, reliability and range. The Shimano FC-MT511 32T crankset pairs with the Deore CS-M6100 10-51T cassette to offer an ultra-wide gear range (510% ratio), perfectly suited to steep climbs and fast sections.
• Deore M6100 Derailleur and Shifters: Millimetric shifting precision, proven ergonomics and resistance to harsh conditions characterize this high-performance groupset.
• Shimano MT401/MT410 Hydraulic Braking: 160 mm Centerlock discs front and rear, progressive power and exemplary modulation for total control in all circumstances.

Wheels and Geometry

• 29-inch Wheels: The preferred wheel diameter in XC, 29" rolls over obstacles better, maintains momentum and offers superior traction. Shimano MT400/MT410 Boost hubs mounted on robust double-wall aluminum rims.
• Michelin Country Grip'R 29x2.1" Tires: Versatile compound ensuring grip, longevity and optimal performance on technical trails as well as flowing singletrack.
• Frame Sizes: Three sizes available (M 16-17" for 156-177 cm / L 18-19" for 170-182 cm / XL 20-21" for 182-198 cm) allowing perfect adjustment to each rider's morphology.

Cockpit and Finishing

The cockpit is based on a Romet aluminum 720 mm / 31.8 mm handlebar offering control and comfort, paired with a 90 mm aluminum stem. The aluminum seatpost (30.9 or 31.6 mm depending on model year, 350 mm length) supports the renowned Selle Italia X-Base saddle, designed for long distances. The FP-971 aluminum pedals complete a coherent and durable equipment package.
