Mountain biking is one of the most varied cycling disciplines and probably the most demanding when it comes to equipment. While full suspension bikes offer amazing riding characteristics, the classic hardtail remains one of the purest tools for the job. Merida’s classic hardtails are the backbone of their range and showcase the enormous wealth of experience and knowledge we could gain in over half a century of bike production and manufacturing. The Big Nine range represents the symbiosis between modern frame technology, attention to detail and craftsmanship 'Made in Taiwan' symbolizes.
The Big Nine TR 5000 is ready to push beyond what cross-country hardtails should do. With relentless speed and low weight uphill, paired with trail-hardtail swagger on the descents. The updated CF carbon frame offers truly progressive geometry with patented AGILOMETER sizing, increased standover clearance and handling stability to better deal with the tough racetracks of today, this down country ready TR option also boosts fork travel and adds in aggressive tyres and a dropper post. Add in the precision and benchmark reliability of Shimano's XT 12-speed and you're good to go.
