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 Singlespeed is the purest expression of that idea - a singlespeed freeride machine built to take massive hits and throw style on every A-Line.
The Cosmic-painted frame rolls on 27.5-inch wheels front and rear, giving you the perfect balance between playfulness and control. Up front, the RockShox Zeb Select fork with a Charger RC damper and 190mm of travel swallows the biggest drops, while the RockShox Vivid Base shock keeps the rear end smooth and predictable.
The drivetrain stays simple and bombproof with a singlespeed setup and Dartmoor’s own chain tensioner, powered by the new FSA Comet Heavy Duty crankset.
Wheels are built on Dartmoor Shield Wide rims, paired with a Boost Expert Singlespeed hub, running on Maxxis Minion DHF MaxxTerra EXO+ tires - proven freeride grip and durability.
The cockpit features the new Thunder CNC-shaped stem and a 35mm Viper Pro handlebar made from 7050 alloy for maximum strength and control. Stopping power comes from SRAM Maven brakes - all the braking performance you will ever need.
