S&M Fastpitch Fork

Product Overview

The S&M Fastpitch Fork is a full chromoly BMX fork with 13mm offset designed for quick, responsive steering. Built with double-butted, tapered legs and a one-piece CNC-machined steerer tube, it provides strength and precision for technical street riding and park sessions. The minimal offset creates agile handling characteristics preferred by riders who prioritize quick steering response.

Key Features

• 13mm offset – Significantly reduced rake compared to traditional 33mm forks creates quicker, more responsive steering for technical tricks and tight transitions
• Double-butted, tapered chromoly legs – 4130 chromoly construction with butted tubing (1.25" to 0.75" taper) places material where strength is needed while reducing excess weight
• One-piece CNC-machined steerer tube – Integrated bearing race machined from solid 4130 chromoly eliminates weak points found in pressed race designs
• Extruded 6061 steerer tube insert – Aluminum reinforcement inside steerer tube adds rigidity and prevents deformation under stem torque and impact loads
• Laser-cut 3/8" dropouts – Precision dropouts ensure accurate wheel alignment and secure axle retention for reliable brake and hub performance
• 2.3" tire clearance – Accommodates modern tire sizes up to 2.3" width without rubbing during compression or hard landings
• 4Q post-weld heat treatment – Baked heat treatment process relieves stress from welding and restores material properties for maximum strength
• M24 x 1.5 compression threading – Standard top cap threading with 6mm allen slot for integrated headset compression systems
• 315.5mm axle to crown height – Lower profile compared to standard forks contributes to responsive geometry

Compatibility and Ideal Use Cases

This fork fits frames with integrated or internal headsets (1-1/8" steerer tube diameter) and 3/8" front axles. The 172mm steerer tube length accommodates most BMX frames and headset stack heights, but verify your frame's requirements before ordering (steerer can be cut down but not extended). Ideal for technical street riders, flatland riders, and park riders who prioritize quick steering response and agility over stability at high speeds. The 13mm offset creates significantly different handling than traditional 33mm forks—steering is much more reactive and immediate, which benefits technical tricks, sharp transitions, and quick direction changes but requires adjustment if coming from standard offset forks. Not recommended for riders who prioritize high-speed stability or transition riding where predictable, stable handling is preferred. The 2.3" tire clearance accommodates most modern street and park tire sizes.
