Description

The kids are alright, and we came up with sweet tooth builds for the promising riders! We understand smaller or "just starting" rippers who demand the best bike birthday money can buy. Rocbird and its Junior versions have updated frame aesthetics as enduro/singletrack machines to make climbs easier and descents even more playful. The new progressive Horst suspension design has been updated for trail geometry, and the mullet wheels setup provides a superb track feeling!

The Rocbird's modern progressive geometry 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 a screw-in bottom bracket type, as we believe it's the best type of BB for MTB frames, because of its 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.

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.
