Mountain biking is all about your limits. The more difficult trails you ride the bigger fun you may have if shred it with a well-designed frame! Thunderbird CF is an all-new carbon enduro frame, dedicated to the difficult terrain and riding conditions. With a perfect lateral stiffness, it is a great 29-er enduro machine with aggressive geometry and 160mm of progressive frame travel. Thunderbird CF will work great with the modern heavy-duty forks with 160-170mm travel. Despite the big wheels, the new Thunderbird CF has the Dartmoor DNA and it will not let you down on big jumps, drops, or even in bike parks. For keeping the frame trouble-free, all pivot points are working on the stiff axles mounted on the sealed Max type bearings. The progressive suspension design of the Thunderbird CF is perfect for both types of shocks: spring shocks and large volume air shocks. The construction reduces also the negative impact of braking on the suspension operation. Front triangle and seat stays are made of high-quality carbon fiber with increased wall thickness for better stiffness. The massive rocker is made of one piece of forged aluminum. To ensure the proper strength and durability the whole chainstay and the inserts in the points that are the most exposed to overload in carbon material are made of aluminum as well.

Before we decided to launch the Thunderbird CF frame for mass production, it not only passed a series of tests on a load machine, where the overloads were much greater than required by the standards but it was also strictly tested on the toughest trails of many European enduro races by our team riders: Marcin Motyka – a legend of the Polish bicycle scene and Olaf Odziomek – a young gun on the Polish enduro  scene. Another period of testing was including uncompromised shredding in the Austrian, Czech and Polish bike parks, where our R&D Jan Kiliński was checking the strength of the frame on the high drops and long jumps.
The Thunderbird CF is available either without a shock or with the highend Fox X2 Factory air shock with high-speed/low-speed compression and high-speed/low-speed rebound adjustments, with 2-pos. Open/Firm  lever, coated with a Genuine Kashima coat. Thunderbird CF frame is equipped with SRAM Universal Derailleur Hanger (UDH). With this frame, you can #ShredLikeThunder!
