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
