FR stands for freeride

, and this is what you should do with this bike. A new 

Thunderbird FR frame

 sits on 27.5” 

wheels, as they are easier to get than 26” nowadays. Coil or air - it is your choice where you want to play with it. 

We designed it for bikepark laps with friends that choose double black diamonds for a warm-up run. It is a pro-

gressive and stiff as hell platform ready to be wrapped, hucked, and mistreated regularly. Thunderbird FR pedals 

just right to keep the sweat off during beer runs while its suspension stays responsive enough to prevent cold 

ones from ruffling. Well, that is what our R&D team says. 180mm of rear and up to 200mm of front travel with 

geometry allowing to fit a 29-inch front wheel means you can easily match it with a dual crown fork and keep the 

eyes away from your lovely mullet. With a great price-to-build ratio, you can easily save on a bike and travel more!
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 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. If you look 

for some more tech talk - the head tube is ready to take the new generation of 1.8” tapered forks with 68-69mm 

crowns and the dropout is compatible with the SRAM Universal Derailleur Hanger (UDH).
