Big Nine 20 2025

Merida's heartland has always been bombproof aluminium hardtails. Half a century of frame building experience counts for a lot.

All Big Nine and Big Seven models use a sophisticated TFS frame featuring the latest technology:

• Full internal cable routing for a clean, neat set up,
• Tapered headtube offering the potential for future upgrades
• Inboard disc brake mounts protect the brake and maximise stopping power

As much Shimano componentry as possible has been added to complement the modern frame and enhance reliability.

There are a wide range of sizes; Big Nine for taller riders and Big Seven for shorter riders with a healthy overlap between the two.

For riders in the middle, riding style can be taken into account. If you are looking for speed and efficiency choose a Big Nine, if you are looking for agility choose a Big Seven.

Features:

• Sophisticated aluminium frame
• Tapered head tube and internal cable routing
• Hydraulic disc brakes
• 1 x 8 Shimano drivetrain
• Lockout fork
• Shimano hubs & chainset
