2025 Merida Big Nine 80 Dark Red/Black

Season:2025

Brand:Merida

Code:P-Q415

The 2025 Merida Big.Nine 80 is the ideal companion for both weekend mountain bike adventures and rugged, everyday use. Built with a high-quality double-butted aluminium frame, it offers a blend of comfort, control, and durability. With its 29er wheels and more upright geometry, this hardtail mountain bike is designed to handle various terrains while providing a comfortable ride, making it perfect for riders seeking both adventure and utility. The RockShox 100 mm air suspension fork absorbs bumps and can be locked out for efficiency on smoother trails or roads, while the Shimano 9-speed drivetrain and powerful hydraulic disc brakes ensure precise shifting and reliable stopping power.

Key Features:

  • Double-butted aluminium frame: Strong yet lightweight, offering smooth performance with 29er wheels.
  • Comfortable and upright geometry: Less aggressive, providing maximum control and comfort for both rough terrain and daily use.
  • RockShox Judy TK 100 mm travel air suspension fork: Includes lockout for enhanced pedaling efficiency on flatter surfaces.
  • Shimano 9-speed drivetrain: Durable and reliable, offering a wide gear range for tackling steep climbs and fast descents.
  • Hydraulic disc brakes: Shimano MT200, delivering powerful and consistent braking performance, no matter the conditions.
  • Internal cable routing: Clean, sleek look with reduced cable exposure for better protection.

The BIG.NINE series is Merida's long-standing flagship line of hardtail mountain bikes. With over half a century of frame-building expertise, Merida has crafted these bikes with modern technologies and geometry. The BIG.NINE 80 is part of a larger family that spans both carbon and aluminium frame options, offering something for every rider, from racing enthusiasts to trail explorers. The updated geometry offers more standover clearance and handling stability, making it capable of handling rougher, more demanding tracks, while the less aggressive geometry of the TFS and SPEED models provides a more comfortable riding position, perfect for long days in the saddle.

Versatile Design:

The BIG.NINE’s 29er wheels roll over obstacles easily and maintain momentum on varied terrain, while the upright geometry encourages control and comfort. Whether you’re navigating technical trails or using it as a reliable commuter, the BIG.NINE 80 is a true all-rounder. The sophisticated TFS frame includes internal cable routing, a tapered headtube for future upgrades, and inboard disc brake mounts for optimal braking power and protection.
