The Flanders Koppenberg is a complete new model for 2021. Embracing all the new technology you would expect in the ever evolving cycling industry. Resulting in some major changes from our previous Zero. Including a refined new monocoque Aero frame and fork with increased stiffness and ride quality . Integrated one piece Aero handlebar and stem with full internal cable routing. We have also increased tyre clearance to allow up to a 32c tyre honouring our Belgian heritage. We run 160mm rotors front and back to maximise braking power while maintaining tyre traction. Thru axle are 100x12mm front and 142x12mm rear to increase lateral stiffness and because of the safety benefits and reliability when coupled with disc brakes. Complete internal cable routing makes for a clean design and will maintain optimal gear shifting in adverse condition. We have also increased our sizing option 46,49, 52, 54, 56, 58 . Along with all these changes we still offer a custom build which includes stem/bar and crank options at no extra charge. All of our build options come with tubeless wheels. While still offering SRAM Force 22, Force AXS and Red AXS group set options. This year we are also offering SRAM Force1 1x drive system with wide range cassettes to give a cleaner simple drive system.
