S&M Widemouth 26mm Offset BMX Fork

The S&M Widemouth Pitchfork is a USA-made 4130 chromoly BMX fork available for 20" and 22" wheel sizes, built around a 26mm offset for a more responsive front end than longer offset forks. The reduced offset shortens the overall wheelbase, making steering quicker and lowering the balance point threshold for technical riding including nose wheelies and pivots.

Key Features

• 26mm offset — Shorter offset than the common 1" (25.4mm) moves closer to straight, reducing trail and making steering more immediate and responsive; also shortens the overall wheelbase for a more maneuverable feel across the whole bike
• Double butted, tapered 4130 cro-mo legs — Butted legs remove material from low-stress mid sections while retaining thickness at the crown and dropout ends; tapering adds stiffness without adding weight
• Laser cut 3/8" dropout slots — Precision laser cutting produces clean, accurate dropout geometry; 3/8" axle slot width accommodates standard BMX axles
• 1-piece CNC machined 4130 cro-mo steerer tube — Single piece machined steerer eliminates joints or welds in a high-stress area; integrated bearing race removes the need for a separate press-fit race
• Extruded 6061 steerer tube insert — Aluminium insert inside the steerer tube adds stiffness and reinforces the steerer against compression and lateral forces from stem clamping
• 173mm steerer tube length — Provides adequate length for standard stem and spacer setups including gyro configurations
• M24 x 1.5 compression with 6mm Allen slot — Standard compression bolt spec compatible with conventional top cap and star nut or compression plug setups
• 2.45" maximum tire clearance — Accommodates up to 2.45" wide tires without clearance issues even at full tire width
• 4Q baked post-weld heat treatment — Stress relieving heat treatment applied after welding strengthens the weld zones and improves overall fork integrity under repeated impact loading

Compatibility and Ideal Use Cases

Compatible with 20" and 22" BMX wheel setups — confirm axle to crown height suits your frame's intended wheel size before ordering. The integrated bearing race requires a compatible headset — confirm headset spec against your frame's head tube before purchasing. The 26mm offset and shortened wheelbase make this fork particularly well suited to technical street riding where nose wheelies, pivots, and balance point tricks are a focus. Maximum 2.45" tire clearance accommodates most current BMX tire widths without fitment concerns.
