Size Specific Wheels: Dependent on frame size we offer 650B or 29er versions on our TFS and SPEED frame level. The requirements of smaller riders (reduced standover height, preferred lower cockpit) are best met by 650B on S and M frame sizes whilst at the other side of the spectrum, L and XL only come with 29er wheels. Size M is available in either 650B or 29er.
New Speed Frame: Following in the footsteps of the TFS frame which was introduced in 2018, the SPEED frame is now in line to get a makeover for 2019. The introduction of slim tube shapes creates a new look and a more relaxed geometry, through a shorter top tube and a higher head tube, resulting in a more upright riding position and enhanced trail visibility. The new frame also comes with IS brake mounts that are positioned within the rear triangle as well as with kickstand and fender mounts.
Dropper Post Ready: All models down to the BIG.NINE 40 feature a 30.9 mm seatpost, the enhanced connection area increases the strength around the top tube/seat tube join and allows the option of fitting a dropper seat post. Models down to BIG.NINE LIMITED allow internal cable routing for the dropper post while the remaining models would require external routing.
Smart Entry: Cables, housings and brake hoses are clamped under tension to prevent rattling when the trails and roads get rough. All inlets are completely interchangeable to deal with Di2, hydraulic hoses, brake cable and gear cable housings etc.
Modern Hardtail Geometry: Our carbon (CF) and aluminium (LITE) models feature a long 422 mm reach, steep 73,5° seat angle, slack 70° head angle and an 80 mm stem (frame size M), affording the next generation XC geometry. Aggressive agility meets stable calmness; perfect for today’s demanding courses.

In September 1972, Ike Tseng (1932–2012) a brilliant engineer and visionary founded MERIDA. While visiting the USA, Ike saw a sign in a bike shop that stated refusal to repair any Taiwanese bikes, due to the unfavourable quality. As a result of this he set out to fulfil his dream of high quality bikes made in Taiwan and formed the MERIDA Industry Company Ltd.
The MERIDA name has three syllables Me-Ri-Da and it is the company’s intention to manufacture beautiful, high quality bikes that enables everyone to reach their destination enjoyably. MERIDA created a world-leading bike factory but Ike still wasn’t satisfied, so in 1988 the MERIDA brand was launched. Ike’s vision is still very much a part of MERIDA, manufacturing all kinds of bikes from children’s bikes to world-class professional road and mountain bikes for the Bahrain- MERIDA team riders. Everybody has a different journey, and everyone can benefit from a MERIDA.
