Compared to the WEAPON TURBO D24, the D29 features significant upgrades across the crank arm, axle, and bottom bracket for unmatched performance:
- Lighter & Stiffer Crank Arm – Upgraded from T6061 to T7075 alloy with an inner hollow design. Weight reduced from 402g → 353g, offering superior stiffness with less weight.
- Faster & Lighter Bottom Bracket – Refined design reduces weight from 98g → 75g, improving efficiency and responsiveness.
- Stronger, Larger Diameter Axle – Increased from 24mm → 29mm, delivering greater stiffness and stability while remaining lightweight.
- Upgraded Chainring Bolts – Changed from alloy steel to T6061 alloy, cutting weight from 13g → 9g.
- Optimized Q-Factor – At just 140mm, ensuring an ideal riding position for both track racers and fixie riders.
- Super Stiff Chainring – BCD 144 with 4mm thickness responds instantly to explosive sprints and high power output, while maintaining reliability.
- Ultra-Light Complete Build – The full set (bottom bracket, crank arm, axle, spider, and 50T chainring) weighs only 640g, outperforming industry benchmarks like Vision Disc Track (818g), Rinpoche R3230 (800g), and Rotor ALDHU (790g).
The WEAPON D29 isn’t just another crankset – it’s a leap forward in track performance, giving you the edge to ride faster, lighter, and stronger.
