3. DARTMOOR THUNDERBIRDS 

Thunderbird CF 

is an all-new 

carbon enduro frame

, dedicated to the difficult terrain and riding conditions. 

With perfect lateral stiffness, it is a great 29-er enduro machine with aggressive geometry and 160mm of pro

-

gressive frame travel. Thunderbird CF will work great with the modern heavy-duty forks with 160-170mm trav

-

el. 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. The 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 rider Marcin Motyka - a legend 

of the Polish bicycle scene. Another testing period included 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.
