Machinez Bars - Corey Martinez Signature BMX Handlebars

The Corey Martinez signature handlebars are a two-piece 4130 chromoly bar built to Martinez's preferred geometry for street and park riding. At 9.25" rise and 30" width, they sit in a range that suits a wide variety of rider sizes and styles. Seamless tube construction throughout eliminates weld points along the tube body, improving structural integrity without adding weight.

Key features

• 100% seamless 4130 chromoly construction — Seamless tubing is drawn from a solid billet rather than welded along a seam. This produces more consistent wall thickness and better fatigue resistance, particularly at high-stress points.
• 9.25" rise — A mid-to-high rise that positions the rider more upright, reducing lower back strain during extended sessions. Works well for riders who prefer a taller front end or run a low front load.
• 30" width — Ships full width so you can cut down to your preferred stance. Most riders run 28"–29.5"; leave excess until you've dialed in your setup.
• 10° backsweep / 2° upsweep — The backsweep pulls the grips slightly toward the rider for a more natural wrist angle and less forearm fatigue. The 2° upsweep complements this geometry without dramatically altering bar feel.
• Straight gauge tubing — Uniform wall thickness throughout. A proven construction approach that delivers consistent strength across the full bar.

Compatibility & use cases

• Clamp compatibility: Standard 22.2 mm (7/8") crossbar. Fits all standard BMX stems. Not compatible with oversized (OS) stems.
• Disciplines: Street, park, and trails. The geometry is versatile for general riding; the high rise makes it less suited to racing or flatland.
