Chris Canfield, a former downhill racer and experienced suspension designer, has launched his new project, Vampire Bikes, with the debut of the Fastarossa DH frame. This innovative downhill bike incorporates three adjustable pivots, three travel settings, and three rear wheel paths, making it a highly versatile “quiver killer” designed to adapt to a wide range of riding conditions. The Fastarossa DH is built around Canfield’s CF3 suspension system, which is the result of decades of suspension design expertise and includes three foundational patents.
Key Innovations:
- Canfield Balance Formula (CBF):
- A virtual pivot design that keeps the Instant Center aligned with the top of the chain for maximum pedaling efficiency.
- Eliminates brake jack and brake squat, ensuring balanced braking performance.
- This technology is already used in Canfield and Revel bikes.
- CF3 Suspension (Chris’ Formula Three):
- The Fastarossa DH features three main pivot positions (low, mid, and high), allowing riders to adjust the bike’s travel and rear axle path.
- Travel options: 165mm (low), 180mm (mid), and 220mm (high). The shock curve remains consistent, with adjustments to leverage ratio for each setting.
- Swapping pivot positions takes just minutes, enabling riders to tailor the bike’s performance to different terrains and riding styles.
- This system transforms the bike into a versatile tool, capable of everything from enduro-like efficiency to full-on downhill performance.
- I-Track Suspension:
- A dynamic idler pulley system licensed from Australian designer Hugh McLay.
- Mounted on the swingarm, the I-Track pulley increases anti-squat as pedal force increases, enhancing stability under power.
- The system’s effect is strongest early in the travel, diminishing as the bike moves deeper into its stroke.
Tech Details:
- Frame Construction:
- Reinforced 4130 steel front triangle for vibration dampening and impact control.
- 7005 aluminum seatstays, chainstays, and linkages for lightweight stiffness.
- Travel & Adjustability:
- Rear travel ranges from 150mm to 220mm, depending on the pivot position and shock stroke length.
- Flip-chip for 29″ or 27.5″ rear wheel compatibility.
- Drivetrain & Brakes:
- Chainstay-mounted I-Track idler pulley, interchangeable with a chainguide in the low pivot position.
- BSA threaded bottom bracket, ISCG05 tabs, and Boost 148mm spacing.
- Not compatible with SRAM Transmission.
- Other Features:
- External cable routing with stealth dropper post routing.
- IS44/56 tapered headset, 34.9mm seatpost (includes a shim for 31.6mm droppers).
- 180mm post-mount rear brake, 73mm BSA threaded BB, and mounts for one bottle cage plus one tool carrier cage.
Design & Aesthetic:
- The frame features batwing rocker links and batwing headtube gussets, staying true to the vampire theme.
- The website includes animated bats, adding a quirky touch to the brand’s identity.
Pricing & Availability:
- The Fastarossa DH frame is priced at $2998 (without a rear shock) and is available in four sizes (S-XL) and three colors: Twilight white, Coffin Nail black, and Blood red.
- Chris Canfield offers assistance in selecting the appropriate fork and shock for each rider’s build.
- The frame is available now in select color and size combinations.
Summary:
The Vampire Fastarossa DH is a groundbreaking downhill bike that combines CBF, CF3, and I-Track suspension technologies to deliver unmatched versatility and performance. Its three adjustable pivot positions allow riders to fine-tune travel, rear axle path, and handling characteristics, making it suitable for a wide range of downhill and enduro terrains. With its robust construction, innovative suspension design, and customizable features, the Fastarossa DH is poised to be a top contender in the downhill bike market.
