Description

Single chainring equipped entry-level 29er aluminium hardtail featuring a more upright and, therefore, more comfortable riding position than our more race-focused hardtails. The riding position puts less strain on the lower back and also improves the visibility of what lies ahead. A 100 mm suspension fork from SR Suntour and hydraulic disc brakes improve comfort and control even further.

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. Our 29er wheel equipped BIG.NINE range comes in carbon and aluminium and features multiple geometry options. The updated CF carbon and LITE aluminium framed BIG.NINE offer truly modern geometry with increased standover clearance and handling stability to better deal with the tough race tracks of today, with downcountry ready TR options that boost fork travel and add in aggressive tyres and dropper posts. The more relaxed geometry of the BIG.NINE TFS and SPEED offers a more comfortable, upright riding position. Our classic hardtails are the backbone of our 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' symbolises.
