Dartmoor

Passion drives perfection. That’s why we took our Thunderbird FR frames pursuing the ultimate freeride setup - the holy grail of all A-Lines. The updated chassis features a lowered center of gravity for enhanced stability and cornering control. Geometry has been optimized for mullet compatibility, ensuring balanced handling across wheel configurations. Revised sizing delivers improved fit and rider ergonomics. The result: a frame that once impressed, now it's mind-blowing.

With either a 200mm dual crown or a 180mm single crown fork, it's designed for bikepark laps with friends who choose double black diamonds for a warm-up run. 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.

Thanks to its high leverage ratio at the beginning of travel, Thunderbirds easily overcomes friction, ensuring that the initial part of the travel is sufficiently soft. At the end of the stroke, higher progression offers resistance against bottoming out, guaranteeing the bike can handle whatever challenges you encounter.

All-aluminum Thunderbird frames are designed to be compatible with the new generation of 1.8" tapered forks featuring 68–69mm crowns. Bigger means stronger — a crucial advantage in Superenduro and Freeride riding. Of course, these frames also work perfectly with standard tapered forks with 1.5" steerer tubes. And when you purchase our Storm or Storm Intro headsets, both crown races are included.

The massive rocker is made of one piece of forged aluminum, keeping lateral stiffness high and providing an on-trail feel even in rough terrain.

Thunderbird frames are fully compatible with a SRAM Universal Derailleur Hanger (UDH) and Eagle Transmission drivetrains.

Our custom bicycle frame protectors are crafted from thick thermoplastic elastomer material, offering superior impact resistance against scratches, dents, and impacts. Designed with a ribbed pattern for added durability, these protectors provide a perfect fit for Thunderbird frames, ensuring maximum protection without compromising aesthetics.

All bearings in our full suspension frames feature extra dedicated custom sealing for enhanced protection against dust, dirt, and moisture. Red Mobil grease provides effective lubrication over extended periods, ensuring minimal friction and optimal performance. MAX-type bearings offer over 30% more load capacity than caged bearings.

180mm of rear and up to 200mm of front travel with geometry allowing you to fit a 29-inch front wheel, which means you can easily match it with a dual crown fork and keep the eyes away from your lovely mullet.
