Aggressive geometry and 160mm of progressive frame travel. Thunderbird CF will work great with modern heavy-duty forks with 160-170mm travel. The progressive suspension design of the Thunderbird CF 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 ensuring the bike can handle whatever challenges you encounter.

Front triangle and seat stays are made of high-quality carbon fiber with increased wall thickness for better stiffness. To ensure the proper strength and durability of the whole chainstay, the inserts in the points that are the most exposed to overload in carbon material are made of aluminum as well.

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.

Yes, we know – mechanics hate that – but we all want to have clean and nice-looking bikes. With that feature, all frames are at least 10% more stylish.

Thunderbird CF 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. It’s possible to adopt both protectors also on the alu version of Thunderbirds.

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 provide 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.
