The Merida One-Forty 400 brings the progressive geometry and suspension design of Merida's ONE-FORTY platform into a more accessible aluminium package. Designed to balance climbing efficiency with descending capability, it's a versatile trail bike for riders who enjoy everything from flowing singletrack to steeper, more technical terrain.

The Lite III aluminium frame uses Merida's FAST suspension kinematics, providing 143mm of rear travel. Its Next Generation enduro geometry features a steep 80-degree seat angle, helping position the rider over the pedals for climbing, while a 65-degree head angle and longer reach provide stability and confidence on descents.

A relatively low front end and bottom bracket contribute to the bike's handling, while Merida's AGILOMETER sizing system allows riders to choose their preferred reach and handling characteristics rather than relying solely on traditional frame sizing. Riders can opt for a shorter frame for a more manoeuvrable feel or a longer frame for additional stability.

Merida also adjusts the suspension's progression across frame sizes, helping the suspension characteristics better suit different rider weights and riding demands.

The frame features internal WIRE PORT cable routing for a clean appearance, along with a threaded bottom bracket for straightforward maintenance. Boost axle spacing, bottle bosses and a trail mount add practicality, while the flip chip provides compatibility with either a mixed-wheel or full 29in setup.

Up front, the Marzocchi Z2 air fork provides 150mm of travel, helping absorb impacts from roots, rocks and rough trail surfaces. Its air spring allows riders to adjust the suspension to suit their weight, while the 44mm fork offset complements the bike's progressive geometry.

At the rear, a Marzocchi Bomber inline shock controls 143mm of travel through Merida's FAST suspension system. The combination is designed to provide traction and comfort over uneven terrain while maintaining the support needed for climbing and pedalling.

Shimano CUES provides a durable and straightforward 1x11-speed drivetrain. The CUES U6000 rear derailleur features Shadow Plus technology to help manage chain movement over rough terrain, while the matching CUES shifter provides simple gear changes from the handlebar.

A Merida Expert TR II chainset uses a 32T chainring, paired with a wide-range SunRace 10-50T cassette and KMC xGlide chain. This gives riders a useful spread of gears, with lower ratios for steep climbs and higher gearing for faster trail sections.

The drivetrain also uses Linkglide technology, designed with durability and consistent shifting in mind. The single-chainring arrangement removes the need for a front derailleur, simplifying gear selection and reducing the number of components to maintain.

SRAM DB4 hydraulic disc brakes feature four-piston calipers front and rear. Their braking power and modulation help riders manage speed on steep descents and technical sections, providing controlled stopping performance when conditions become more demanding.

Merida Comp TR II aluminium rims have a 28mm internal width, providing a suitable platform for wider mountain bike tyres. They're tubeless ready, although tubeless tape and valves are not included, so additional components would be needed for conversion.

The wheels use Shimano TC500 hubs with Boost spacing, featuring a 15x110mm front axle and 12x148mm rear axle. Both wheels use 32 spokes for a durable trail-focused build.

A Maxxis Minion DHF tyre is fitted at the front, with its aggressive tread designed to provide grip and steering confidence on loose and technical terrain. At the rear, a Maxxis Forekaster provides a versatile tread suited to mixed trail conditions.

The specification lists a 29x2.5in Minion DHF front tyre and a 29x2.4in Forekaster rear tyre. However, the rim specification identifies a 29in front wheel and 27.5in rear wheel. This discrepancy should be confirmed before publishing the exact wheel configuration.

One of the standout features of the One-Forty 400 is its size-specific Merida Expert TR II dropper post. Travel increases with frame size, providing 150mm on XShort and Short frames, 170mm on Mid, 200mm on Long and 230mm on XLong.

This allows riders to lower the saddle for descents and technical sections, creating more room to move around the bike. The longer travel options on larger frames help maximise clearance without compromising the seated pedalling position.

Merida's Comp TR aluminium handlebar measures 780mm wide with a 20mm rise, paired with a Comp TR stem. This provides a wide, stable cockpit suited to technical trail riding, while the frame's long seatpost insertion depth helps accommodate the dropper post.

The Merida Comp SL saddle incorporates 25% recycled material and features a V-mount system with an included Merida minitool, providing a useful option for carrying essential tools on the trail.

Overall, the Merida One-Forty 400 combines modern trail geometry with a practical component specification. Its Marzocchi suspension, wide-range Shimano CUES gearing, SRAM four-piston brakes and generous dropper post travel make it a versatile choice for riders who want a mountain bike that can climb efficiently and handle demanding descents.

Specification note: The supplied wheel information is inconsistent. The rims are listed as 29in front and 27.5in rear, while both tyres are specified as 29in. I've avoided stating an exact wheel configuration in the Key Features until this can be confirmed.
