Combining the heart of the world's best road bikes with a flat-bar, urban-friendly form, Sirrus Limited redefines the notion of versatility. The super light FACT 8r carbon frame and fork (both with Zertz) is stiff, fast, and highly compliant; while the 2x10 FSA/SRAM Apex drivetrain means lighter weight and flawless shifting.
- FACT IS constructed carbon frame with Endurance Road geometry, Zertz inserts, and tapered head tube delivers the pure speed of a high-end road bike in a flat-bar package
- FACT carbon fork with Zertz inserts for a quick, responsive road feel and forgiving ride
- Adjustable 4-position oversized forged alloy stem with 31.8mm bar clamp for strength and versatile positioning
- BodyGeometry Targa grips lock on and help alleviate hand pain and tingling fingers; integrated bar ends for changing hand position included
- FSA Omega compact alloy crankset with 50/34 configuration for lightweight, wide-range gearing
