Merida Big Nine 40 2026

Start your MTB adventure

The BIG.NINE 40 uses the latest robust yet lightweight aluminium frame as the basis for a high-performance, great-value build. With updated geometry and a 120mm air fork, it's a confident off-road bike that's also versatile enough for everyday use. The Shimano CUES 1x9 drivetrain and hydraulic disc brakes are simple yet effective.
In the demanding world of cross country, the classic hardtail remains one of the purest tools for tackling races. The BIG.NINE range with 29" wheels includes carbon frames and two aluminium versions, offering an experience to suit every budget. The latest CF carbon and LITE aluminium frames feature modern geometries with increased ground clearance and riding stability, ideal for the most demanding race courses. There are also ‘downcountry’ versions with longer forks, aggressive tyres and dropper seatposts. For beginners, the updated BIG.NINE TFS offers a more relaxed geometry and versatile, affordable components, also available in the BIG.SEVEN TFS version with 27.5" wheels, designed for riders with a smaller frame. Classic XC hardtails are the backbone of the range and represent the experience and excellence that distinguish the brand, the result of over half a century of Taiwanese production.
