FIT Series One Fork (20") Gloss Black

FIT Series One Fork (20") Gloss Black

The FIT Series One is a full 4130 chromoly fork designed for 20" wheels, manufactured in the USA. Features laser-cut dropout slots and a one-piece CNC-machined steerer tube with extruded aluminum insert. Requires a standard bearing race (included with most headsets) for installation.

Key Features

• Full 4130 chromoly construction – Legs and dropouts machined from chromoly steel for superior strength and impact resistance compared to hi-tensile steel forks
• Laser-cut dropouts – Precision cutting ensures accurate 3/8" axle slot alignment and clean edges that reduce stress concentrations
• One-piece CNC-machined steerer tube – Eliminates welds in the critical steerer area for increased structural integrity under steering loads and impacts
• Extruded 6061 aluminum steerer insert – Reduces weight in the steerer tube while maintaining strength where the headset bearings seat
• 33mm offset – Positions front wheel ahead of steering axis for stable handling and predictable steering response in street and park riding
• Made in USA – Domestic manufacturing with quality control throughout production

Compatibility and Ideal Use Cases

Requires standard (non-integrated) headset with separate bearing race. Compatible with 20" wheels using 3/8" axles. The 162mm steerer length works with most standard BMX frames but should be measured against head tube length and spacer requirements before ordering. The 33mm offset and 315.5mm axle-to-crown height provide balanced geometry for street, park, and transition riding. Best suited for riders seeking a durable, USA-made chromoly fork who prefer traditional bearing race headsets over integrated systems.
