Merida Big Seven 15 Mountain Bike 2023 - Hardtail MTB

The UK version of the Big Nine and Big Seven 15 have been upgraded to 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.

- 6061 aluminium, double butted and technoformed frame
- SR Suntour XCT30 forks with 10mm of bump soaking travel
- Merida K1080 tyres help keep you in control

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