With the WHISTLER, you get the ideal wheel size to suit your height and needs: The WHISTLER in sizes XL to M comes with 29" wheels. Size S and XS have 27,5" wheels. When faced with risky situations, you need a partner you can rely on. That is why we have equipped our WHISTLER with disc brakes to ensure consistent braking performance and optimal braking behaviour in all weather conditions. We route all cables through the down tube of the frame for better protection of the cables, durability and a clean look. The WHISTLER 3.6 EQP is equipped with everything you need for your daily rides in any weather and light conditions. Mudguards and stand are features as well as a light system with a hub dynamo.
