Freeride has many faces - and the all-new Thunderbird FR family is built to master them all. We scrapped the old geometry and started from the ground up, creating a frame that’s stronger, more agile, and ready for the biggest jumps.
The Thunderbird FR Pro GX is the ultimate bikepark machine from Dartmoor-Bikes. This is the best freeride bike we have ever built, straight out of the box - designed for riders who want to shred. Everything.
At the heart of this bike is our brand new version of Thunderbird FR frame in a stealth matt black finish with mirror silver decals. It runs a mullet setup with a 29-inch front wheel and 27.5-inch rear for the perfect mix of rollover speed and playful control, but you can also run it full 27.5 if you want.
Up front, the RockShox ZEB Ultimate fork in striking Electric Red delivers 190 mm of ultra-controlled travel, combining stiffness and precision worthy of the world’s toughest freeride lines. Out back, the RockShox Vivid Air Ultimate shock provides the perfect blend of sensitivity, adjustability, and support - with that bottomless feel only the new Vivid Air can deliver.
The SRAM GX DH 7-speed drivetrain with an 11–25T cassette keeps the gearing tight, clean, and ready for bike-park speed runs. Tough Patrol welded rims paired with Reel Expert hubs form a durable and reliable wheelset wrapped in Schwalbe Albert Gravity Pro radial-construction tires - the pinnacle of grip, traction, and precision control across any surface.
The cockpit is dialed with the new Thunder CNC-shaped stem and Lightning Hi handlebar for pinpoint steering response. When it’s time to slow things down, SRAM Maven Silver brakes deliver massive stopping power and consistency no matter how steep the line gets.
Send it, Bro!
