MT300 27.5 Inch Mountain Bike with 2×9 Gears
Precision Fit & Trail-Focused Sizing
Available in three frame sizes to ensure the right fit and confident handling across different rider heights:
-
16" (Size S): Suitable for riders approx. 160–175 cm
-
18" (Size M): Suitable for riders approx. 170–185 cm
-
21" (Size L): Suitable for riders approx. 175–198 cm
Each size features balanced, trail-oriented geometry designed to support proper riding posture, control and comfort on cross-country rides and longer trail sessions.
Lightweight Aluminium Frame with Internal Cable Routing
The upgraded aluminium frame uses internal cable routing for a clean appearance while protecting cables from dirt, moisture and trail debris. Lightweight yet robust, it offers responsive handling and a refined, modern look without unnecessary complexity.
Suspension Control & Confident Braking
An oil-spring suspension fork with adjustable preload and mechanical lockout adapts easily to changing terrain—lock it out for efficient climbs or open it up for added comfort on rough descents. MT200 hydraulic disc brakes provide smooth lever feel and reliable stopping power in wet, muddy or uneven conditions.
Efficient 2×9 Drivetrain
The CUES 2×9-speed drivetrain delivers a wide and practical gear range with smooth, consistent shifting. Compared with traditional triple setups, it simplifies operation while retaining versatility for climbing, cruising and faster trail sections.
Puncture-Resistant 27.5" Trail Tyres
Fitted with 27.5 × 2.1" tyres featuring reinforced casing to help resist punctures from sharp debris. Deep tread patterns improve grip on loose terrain, while supportive sidewalls enhance stability through corners, making them suitable for trails, paths and mixed riding conditions.
