Simon Metzner of Actofive is displaying his today’s CNC machined introduction at Bespoked 2022; the P-Train one hundred sixty five. It is the German brand’s long-tour bike constructed particularly for enduro racing. It capabilities the identical high-pivot linkage because the P-Train 145, consequently handing over a rearward axle course that necessitates using an loafer pulley, however the new bike advantages from the addition of a floating brake arm that allows to isolate suspension motion from rear wheel braking forces.

The today’s Actofive P-Train is a modular platform that may run 145mm, 155mm, 165mm or 175mm rear wheel tour, depending on the mixture of hyperlink and surprise. It replaces the unique P-Train that became restrained to simply 135mm or 145mm touring, beefing up to satisfy the needs of EWS Racing.
High-pivot bikes and their rearward axle paths supply an exceedingly solid journey feel, however they do necessitate a few extra hardware to manipulate the developing rear-middle duration. The loafer pulley routes the chain in the direction of the principle pivot to cope with chain boom and its unwanted outcome, pedal kickback. On the brand new P-Train Enduro Bike proven at Bespoked, there are viable positions for that loafer pulley.
Shown right here withinside the decrease of the 2 positions, the loafer is positioned in the higher role for pedalling. The better roll, that places the chain in the direction of the principle pivot, is higher for descending because it reduces pedal kickback further.

Vojtěch Bláha is Actofive’s EWS Racer, and his remarks proved beneficial to designer, Simon Metzner, in the improvement of the brand new longer-tour platform. He commented that the P-Train’s suspension had a bent to stiffen up below braking, something that is clearly an outcome of the anti-upward thrust traits of the linkage design. Thus, a key replace to the P-Train is the addition of a floating brake arm, or the Brake Torque Support, as Actofive name it.
The arm extends from the rotating hyperlink to the dropouts, with an outboard bearing permitting the brake mount to pivot approximately the rear axle. This isolates a number of the braking forces from suspension motion. It’s subtle, however in the above video you could see the brake mount and the swingarm getting large as Simon pushes the P-Train one hundred sixty five via the preliminary 50% of its rear wheel tour.

The above graph suggests how the presence of the Braking Torque Support impacts the anti-upward thrust homes of the P-Train’s suspension platform.
The Actofive -P-Train has a 437mm chainstay duration on the “Long” body size – that will increase with the aid of using a most of 23mm because the rear wheel is driven via the tour
A 210mm x 55mm surprise promises 145mm or 155mm of rear wheel tour, whilst the 230mm x 65mm surprise bumps tour as much as a probable 165mm or 175mm. The body is designed to run a fork among 160mm and 190mm tour. The P-Train one hundred sixty five may be installed as a whole 29er, or with a mixed-wheel configuration. Geometry is adjustable to account for the alternate in backside bracket height. Head perspective is adjustable too with using a 1° angleset; the slackest configuration promises a 63° head perspective.
The Actofive P-Train one hundred sixty five consists of skinny walled CNC machined halves of 7075 Aluminium, bonded collectively with a unique adhesive
