Dartmoor Rocbird Mullet 29"/27.5" Frame without shock, for 205x65mm / 185x50mm shock, Anthracite Flash with Mirror Decals, Large

The Dartmoor Rocbird in Large size is offered here in a 29"/27.5" mullet configuration, delivering a balanced mix of front-end stability and rear-wheel agility. The 29” front wheel increases confidence on steep and fast sections, while the 27.5” rear wheel improves maneuverability in tight and technical terrain.

The refined geometry preserves the agile Rocbird character. A short rear triangle — still under 440 mm — keeps the frame responsive and predictable when pushing the pace.

Lighter than Dartmoor’s aluminum Thunderbird frames, the Rocbird is well suited for enduro and trail riding where flow and efficiency matter. The progressive Horst Link four-bar suspension remains active under braking, maintaining traction and control in rough conditions.

Durability comes from MAX bearings with LLU seals, built to withstand demanding riding environments. Thanks to a replaceable shock mounting link, the frame supports two shock sizes, allowing 160 mm or 140 mm of rear travel depending on setup.

The Anthracite Flash finish, featuring a glossy dark tone with mirror decals, gives the frame a bold, technical look that stands out on the trail.
