Product Description

The Merida One-Twenty 7.800 full suspension mountain bike is proof that lightweight & short travel bikes can still shred the trails alongside with bigger machines.

Constructed from a lightweight 6066 aluminium alloy, the Merida One-Twenty MTB is a lightweight-yet-tough little cookie that can hold its own with much bigger machinery. The sophisticated ‘Float Link’ suspension system allows the rear shock to react to even the smallest lumps and bumps in the trail, giving you complete confidence in the bike’s handling, whether you’re out on a long-distance marathon or shredding at a bike park.

Supplied with 27.5” wheels, the Merida One-Twenty 7.800 is available in frame sizes Small, Medium and Large. If you prefer bikes with larger frames and wheels, the Merida One-Twenty 9.800 29er MTB comes with the same specification and price, and is available in sizes Medium, Large and X Large.

Giving the bike it’s 130mm front suspension travel, the RockShox Revelation RC air fork is smooth and supple, and allows you to adjust the rebound damping to find a setting that works for you. At the rear, the 120mm floating Link suspension is kept in check by a Fox Float Performance shock, which gives you three damping modes (Open, Medium, Firm) that can be easily switched from in the saddle.

The One-Twenty 7.800 is treated to SRAM’s latest 1x12 speed GX Eagle drivetrain, equipping the bike with an impressive 500% gear range without the need of a front derailleur. Taking care of braking duties, a pair of Shimano SLX disc brakes use cooling fins to dissipate heat on long descents, allowing them to make full use of the larger 180mm rotors

Defy expectations, with the Merida One-Twenty 7.800 full-sus mountain bike.
