The ambition of the WEAPON Bullet-Pro aero track frameset is to become one of the best alloy track frames in the world.
Compared to the bullet-style aero track frame, we have made further optimizations and adjustments to the professional version.
-
A Re-tuned Track Geometry – We have not only increased the down tube’s cross-section from 65mm to 75mm but also enhanced the tubing profile of the rear triangle, significantly improving the frame’s overall stiffness.
-
Aero Carbon Seatpost – To achieve the lightest frame set possible, we upgraded the original aluminum seat post to a carbon fiber seat post, reducing the weight from 430g to 180g, allowing you to enjoy faster cruising and acceleration at any moment.
-
Upgraded Aero carbon fork – For optimal aerodynamic performance, we upgraded the fork while ensuring compatibility with 700×30c tires, giving you more riding versatility.
-
Improved Transmission Efficiency – To enhance drivetrain efficiency, we optimized the chainstay length, shortening it from 390mm to 375mm.
-
More Size options – We added an XXL size to provide more options for riders who love our frames, ensuring a perfect fit for a wider range of cyclists.
This Pro- version maintains technical accuracy while ensuring clarity and fluency for an international audience in the cycling industry

No duties paid in Canada. The frame is light and the paint is mesmerizing. Welds are very smooth. Highly recommended.
Arrived in Seattle. The box was huge and well padded. The color shift is consistent all over. Very happy customer.
Die Oberfläche ist glatt und sieht super aus. Lieferung nach Hamburg war schnell und zollfrei. Chameleon ist der Hammer.
Easy to assemble. Everything fits right. Arrived in Boston quickly. The Chameleon looks expensive. No tax was a bonus.
San Francisco delivery was super quick. Packaging was secure. The Chameleon finish feels very high end. Love it.
