3D steel printing meets handmade carbon precision

Together with german 3D printing pioneer Urwahn we created a bike which brings together the full potential of 3D steel frame printing technology and our own ultimate lightweight carbon bike parts.

Tried and tested

“Once you let this Tiger out of its cage, the only way out is to go forward” was what Track Bike World Champion Stefan Bötticher stated after his testride at the Velodrom.

The details

The Steel: Compared to the competition, this racing bike has a geometric advantage. The elastic suspension of the rear wheel gives the rider additional riding comfort without sacrificing bottom bracket stiffness. This effect is especially noticeable on longer rides and/or uneven surfaces. For the coating of the steel frame, Urwahn relies on a complete copper plating of the 3D printed steel frame. The result shows that they have truely mastered their craft.

The Carbon: Both the TLO Evo handlebar and  TLO saddle unit are trimmed for extreme lightweight construction. The aerodynamic 45mm high profile SL Series carbon clinchers, on the other hand, guarantee maximum directional stability and run towards infinity thanks to the high-quality hub mechanism from Tune. The Force eTap AXS shifting group 1×12 from SRAM is a contemporary wireless shifting system. This once again supports the feeling of operating the shift paddles of a sports car.
