Cross-country racing runs deep in Merida’s history, and the Big Nine 3000 carries that focus into a modern, accessible carbon hardtail. The CF3 carbon frame keeps weight low while maintaining strength, with Boost axle spacing adding stiffness for precise tracking when you push on the pedals or lean into corners.
Merida’s Agilometer sizing system helps match frame size to both rider height and riding style, so whether you want sharp responses or more stability, the geometry works with you. The result is a bike that feels quick on climbs, composed on descents and comfortable over longer distances.
Up front, the RockShox Judy Gold RL air fork offers 100mm of controlled travel to take the edge off roots, rocks and trail chatter. The remote lockout lets you firm things up instantly for smooth climbs or sprints, helping you stay efficient when the trail allows.
Shimano’s Deore 12-speed drivetrain delivers dependable shifting and a wide gear range, making steep climbs manageable without sacrificing speed on flatter sections. Hydraulic disc brakes from Shimano provide consistent stopping power, giving confidence when trails get faster or more technical.
Rolling on 29” wheels with high-volume Maxxis Rekon Race 2.4” tyres, the Big Nine 3000 balances low rolling resistance with predictable grip, so you can carry speed while staying in control. It’s a well-rounded XC hardtail for riders who want to ride further, faster and with confidence off-road.
