A wheel size that fits your height
With WHISTLER you have the ideal wheel size to match your height and needs: WHISTLER in sizes XL to M comes with 29" wheels. Sizes S and XS have 27.5" wheels.

Reliable braking power and integrated design
In risky situations, you need a partner you can rely on. That’s why we equipped our WHISTLER with disc brakes to ensure consistent braking performance and optimal braking behavior in all weather conditions. We route all cables through the frame’s down tube for better protection and durability and a clean look.
