The Merida Big Nine 40 is the perfect entry into mountain biking, delivering a confident, comfortable, and fun ride whether you’re exploring forest trails, canal paths, or hilly terrain. Built around Merida’s TFS V aluminium frame, it offers the ideal balance of strength and low weight. Double-butted, technoformed tubing ensures durability, while smooth welds and internal cable routing give it a clean, premium finish.
Modern trail geometry means a longer reach and shorter stem for stability on descents and precise control through technical sections. The steeper seat angle keeps your weight forward on climbs, while a slacker head angle adds confidence when tackling steeper or rougher ground.
The X-Fusion Migo 32 Air fork provides 120mm of adjustable travel, soaking up bumps for a more comfortable and controlled ride. The air spring allows riders to fine-tune the feel of the fork to match their weight and riding style, while the lockout function improves efficiency on smoother sections or climbs.
The 1x9 Shimano CUES drivetrain is simple, efficient, and easy to maintain. With a wide 11-46T cassette, you’ve got plenty of range for steep climbs and fast descents. Shifting is crisp and consistent, thanks to Shimano’s precise engineering, while the CUES groupset’s robust design makes it perfect for everyday off-road use.
Stopping power comes from Shimano MT200 hydraulic disc brakes, offering reliable performance in all conditions. Paired with 160mm rotors, they deliver consistent braking on wet, dry, or muddy rides.
Rolling on fast and stable 29” Merida Comp CC wheels, the Big Nine 40 keeps momentum over roots, rocks, and rough terrain. Kenda Booster 29x2.4” tyres provide excellent traction and grip, with tanwall options adding a stylish finish.
The cockpit and finishing kit come from Merida’s in-house Comp range, ensuring comfort and reliability. The frame is also dropper post ready for riders who want to upgrade to a height-adjustable seatpost in the future.
