S&M Pitchfork BMX Fork (18", 20", 22", 24", 26")

S&M Pitchfork BMX Fork (18", 20", 22", 24", 26")

The S&M Pitchfork is a double-butted 4130 chromoly fork available in five wheel sizes from 18" to 26". Features laser-cut dropouts, one-piece CNC-machined steerer tube with extruded aluminum insert, and 4Q Baked post-weld heat treatment. Made in the USA with 33mm offset across all sizes.

Key Features

• Double-butted 4130 chromoly legs – Variable wall thickness reduces weight in low-stress areas while maintaining strength where needed, offering better strength-to-weight ratio than straight-gauge forks
• Laser-cut 4130 chromoly 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
• 4Q Baked post-weld heat treatment – Heat treating after welding restores material strength lost during welding process, maximizing durability
• 33mm offset across all sizes – Consistent offset positioning provides stable handling and predictable steering response regardless of wheel size
• Five wheel size options – Available for 18", 20", 22", 24", and 26" wheels to accommodate different bike builds and rider ages

Compatibility and Ideal Use Cases

Requires standard (non-integrated) headset with separate bearing race. Compatible with 3/8" axles. The 162mm steerer length (18"-24" sizes) works with most standard BMX frames but should be measured against head tube length and spacer requirements before ordering. The 26" version includes a longer 203mm steerer and does not include compression hardware. Double-butted construction and 4Q heat treatment make this fork suitable for riders seeking USA-made quality with optimized strength-to-weight ratio for street, park, dirt, and all-around riding. The multiple wheel size options accommodate youth bikes (18"), standard BMX (20"), cruisers (22"-24"), and larger wheel builds (26").
