The modern progressive geometry of the Rocbird allows for a bottomless feel at the end of the curve, accommodating both, spring and air shocks. Each type of shock has its advantages, so the choice depends on personal preference and how the rider prefers their suspension. We aim to accommodate Rider Your Way in all aspects.

The Rocbirds' high leverage ratio at the start of travel helps overcome friction, making the initial part of the ride smooth. Towards the end of the stroke, increased progression provides resistance against bottoming out, ensuring the bike can handle any challenges you encounter.

Are you torn between riding in bike parks or tackling challenging enduro trails with roots, rocks, and mud? The Rocbird can help you with its replaceable shock mount, which allows you to use two different sizes of shocks. This means you can adjust the frame travel to 160mm or 140mm, accommodating various riding styles and preferences.

Our custom bicycle frame protectors are made of thick thermoplastic elastomer material, providing excellent protection against scratches, dents, and impacts. The ribbed pattern design adds durability, and these protectors are specifically tailored to fit Rocbirds frames, offering maximum protection without sacrificing aesthetics.

All Rocbird frames use screw-in bottom bracket type, as we believe it's the best type of BB for MTB frames, because of their durability and easier maintenance. Also, Rocbird frames, thanks to a special cut on the BB shell, can use a dedicated ISCG05 mount, which can be purchased separately. This allows riders to add a chain guide and bash guard, leaving the option open for personal preference.
