Rock Machine Whizz FS III 90 AXS 2025 (Sulfur Yellow)
A versatile bike park beast with 170mm and 160 mm of travel that can take even the most demanding enduro tracks. A very low frame build, a long wheelbase. Added to that is premium RockShox suspension with the ZEB combined with a Vivid, progressive kinematics, room for long dropper posts with a diameter of 34,9 mm, an oversize head tube. The Whizz II is fitted with "mullet" wheels that combine tracking stability with willingness to corner and durability. The SRAM Eagle Transmission shifting is controlled wirelessly, just like the dropper post. We chose SRAM DB8 brakes for their consistently high performance. The WTB Proterra Tough built wheels are equipped with rims with internal reinforcement, EZO bearings, a freehub with engagement every 18° and special Pillar locking nipples for wheel build stability.
Benefits
- A unique frame with carefully tuned ride characteristics, a low top tube and the option to change the travel
- RockShox ZEB and Vivid for a ride like on a flying carpet
- Wireless control of gear shifting and the dropper post
- Sealed bearings, external rear brake routing, a threaded bottom bracket and other solutions for long life and easy maintenance
