Press Release: Actofive Cycles / Fiasko Racing
Actofive Cycles is based in Dresden, Germany, founded by the mechanical engineer Simon Metzner.
With a passion for technology and his vast experience in engineering, Simon´s dream of an own bike frame came true, tailored toward individual preferences: the highest possible pedaling efficiency with an ultra-sensitive suspension. The result is the `P-TRAIN`, named after Helsinki´s airport shuttle train, which combines a steel frame with recently emerging trends like high pivot suspension and CNC-machining.

The welding is done by local partners and experts for tailored-made steel frames. The heat-treated 853 Reynolds tube set, together with the CNC-machined ZS44/ZS56 Headtube give the aesthetic finish. The front triangle, with its elegant, skinny steel tubes, segues into a CNC-machined, high-tech rear end, which delivers 130 mm of travel.
Actofive belongs to Metzner Engineering Ltd., which is a engineering office, focusing on one-hand-engineering- and production services from conception to the finished product. This allows Actofive to manufacture all parts in-house on a CNC milling machine. Special attention is paid to the rear swingarm. Each side of the rear triangle is made from one piece of 7075 aluminum and bolted together with titanium bolts. This guarantees a unique look, as well as high strength and precision.

With the third iteration of the CNC-machined swingarm, work is underway to fulfill the requirements in terms of stiffness, design and performance. This means that the P-TRAIN will be available in a small batch and three sizes (small, medium, large) soon. In addition, a completely CNC-milled aluminum front triangle in a two-piece construction is in the works.
The third iteration of the swingarm is more edgy, more lightweight and compatible to the completely CNC-machined equivalent
