Dartmoor

Simple Horst link design built around proven four-bar suspension is balanced for pedal efficiency and braking to shred factor. The progressive suspension design is perfect for both types of shocks: spring shocks and large-volume air shocks. The construction also reduces the negative impact of braking on the suspension operation.

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 fit with a new generation of 1.8" tapered forks with 68-69mm crowns. Bigger means stronger, and surely that’s important in Superenduro/Freeride.

The massive rocker is made of one piece of forged aluminum. Keeping lateral stiffness on a high level and providing on-trail feeling even in rough terrain.

Thunderbird SE 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.

Rolling on Reel Expert hubs and making noise by wide pawls system with 108 engagement points and a reinforced structure to meet the requirements of modern drivetrains with cassettes generating very high loads when uphilling on a 51T or 52T cog. Each pawl has 2 teeth, catching the ratchet ring simultaneously to increase the reliability of the pawl system.
