There is a completely new model in the Dartmoor-Bikes frame collection! Say hello to Rocbird, the successor to the Blackbird and Bluebird frames. With the new frame construction, this enduro/ singletrack machine will make climbs easier and descents, even more playful. Rocbird has a lighter frame than the aluminum Thunderbirds so it will take some less beating on the most demanding lines, but on most of the enduro trails you will feel the same riding fun, as Rocbird has the progressive Horst suspension design that works flawlessly, even under heavy braking. Rocbird feels bottomless at the curve's end, allowing both spring and air shocks. The combination of a larger wheel at the front and a smaller one at the rear guarantees perfect handling on all types of trails. To increase rigidity and reliability, we used MAX-type bearings with LLU-type seals in this frame. Thanks to the replaceable shock mount, the Rocbird can be fitted with two sizes of shocks and obtain a frame travel of 160mm or 140mm, adapting it to the preferred riding style.
* Rocbird frames are available with or without shocks. Frames without shocks are offered with shock mounts in two lengths, so they can be assembled either with 205x65mm shock as the Enduro version or with 185x50mm shock as the Trail version.
