Understanding the specifications of your dirt jump (DJ) bike is crucial for peak performance at the park or on the streets. If you’re considering the Faction II for your next DJ rig, you’ll want to know exactly what it’s made of and how it performs. This guide breaks down the key specs of the Faction II, ensuring you have all the information you need to shred with confidence.
Key Specs for Your Faction II DJ Bike
Let’s dive into the details that make the Faction II a solid choice for dirt jumping and street riding.
Spindle Size for BMX Cranks
For riders looking to customize their Faction II with BMX-style cranks, the frame is optimally designed for 153mm/6″ spindles. This ensures compatibility and efficient power transfer when you’re launching off jumps or powering through lines.
Warranty for Peace of Mind
The Faction II comes with a 3-year limited warranty, reflecting the manufacturer’s confidence in its durability and build quality. This warranty provides assurance and protection for your investment, letting you focus on pushing your limits.
Headset Compatibility
The Faction II utilizes a FSA NO.42/ACB headset, specifically an integrated style with a 42mm upper and 52mm lower. This standard headset ensures smooth steering and responsiveness, critical for precise bike control in DJ maneuvers.
Frame Material and Weight
Constructed from Reynolds 520 Chromoly steel, the Faction II frame balances strength and agility perfectly. Weighing in at approximately 4.8lb, it’s light enough for spins and tricks, yet robust enough to handle hard landings and street abuse. This material choice is a hallmark of quality Dj Bikes, offering a responsive and durable ride.
Wheel and Tire Sizing
Embrace the 26″ wheel revolution! The Faction II comfortably accommodates 26″ wheels and provides ample clearance for tires up to 2.3″ wide. This tire size offers excellent grip and cushioning for dirt jumps and street riding, maintaining momentum and control.
Bottom Bracket Standard
The Faction II is built with a BMX-style, Mid bottom bracket (BB). For optimal performance and to avoid compatibility issues, it’s recommended to pair your bottom bracket and crankset from the same brand. This ensures a snug fit and smooth operation of your drivetrain.
Steerer Tube Type
The Faction II frame is designed for a tapered steerer tube (1 1/8″ – 1 1/2″). While optimized for tapered forks, it’s versatile enough to accept a straight 1 1/8″ steerer fork when used with an adapter crown race. This provides flexibility in fork selection based on rider preference.
Minimum Steerer Tube Length
When setting up your Faction II, ensure your steerer tube length is sufficient for safe riding. With zero spacers and assuming a 40mm stem stack height, the minimum required steerer length is 165mm, including the frame, headset, and stem. Always double-check based on your specific stem to ensure safe steerer engagement.
Rear Axle Spacing
The Faction II employs 10x135mm BMX-style horizontal dropouts. This rear axle spacing is standard for many DJ bikes, providing a strong and reliable setup for single-speed drivetrains and allowing for chain tension adjustment.
Brake Compatibility
The Faction II is designed for disc brakes only, with a 160mm rotor maximum and an IS Standard brake mount. While disc brakes offer superior stopping power, especially beneficial for more aggressive riding, the frame also allows for a brakeless setup for experienced street riders (though manufacturer discourages brakeless riding).
Axle Security
If you experience axle slippage, especially under hard riding conditions, consider using chain tensioners (axle tuggers). These devices help maintain consistent chain tension and prevent your axle from shifting in the horizontal dropouts.
Derailleur Compatibility
The Faction II is intentionally designed as a single-speed specific frame. It is not compatible with a derailleur. This single-speed setup simplifies maintenance, enhances durability, and is ideal for the demands of dirt jumping and street riding.
Seatpost Size
The Faction II uses a 27.2mm seatpost and features an integrated seat clamp. This standard size is common for DJ bikes, offering a balance of strength and weight.
Conclusion
The Faction II is a well-specified DJ bike frame designed to meet the demands of dirt jump and street riders. Understanding these specifications ensures you can properly build and maintain your bike for optimal performance and enjoyment. Whether you’re dialing in your crank setup or ensuring your steerer tube is the right length, this guide provides the key information to get the most out of your Faction II DJ bike.
