We need to keep up and maybe even add more. Our new carbon Sterk (gravel in Czech) is a step forward in every way. The lowered seatstays add to the bike's comfort and, together with the very short chainstays, add agility and better handling. We added UDH hanger. Hanger is universal and can be found anywhere in the world. This rebuild will also allow the use of the latest SRAM Transmissions shifting on the bike. All wiring runs through the interior, everything is aesthetically pleasing and the wiring no longer gets in the way of any bag under the handlebars.


We use best possible functional parts for best possible gravel performance, there is not neccessary to change parts just after bike purchase. All is tested before on us.
