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 progressive and stiff as hell platform ready to be braapped, hucked, and miss-treated 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).
