Description
Specifications

Upgrade your BMX racing setup with the Promax HF-2 Crankset - a lightweight, high-performance component engineered for durability and precision. Designed for professional riders and enthusiasts alike, this 172.5mm crankset with a 24mm spindle offers optimal power transfer and reliability for intense BMX sessions.

Materials & Construction:

Forged from premium 6061-T6 aluminum, the Promax HF-2 crankarms are hollow-forged to maximize strength while minimizing weight. The robust steel spindle is permanently fitted into the drive-side arm, ensuring seamless power transmission and durability under demanding riding conditions. Its sleek black finish adds a stylish, professional look to any BMX bike.

Performance & Engineering:

Built for BMX racing, the HF-2 crankset features a 104mm BCD chainring mounting pattern, compatible with a wide range of sprockets (chainring sold separately). Its optimized chainline of 43mm and a Q-factor of 168mm provide efficient pedaling geometry, reducing rider fatigue and enhancing stability during aggressive maneuvers.

Components & Technology:

The 2-piece design simplifies installation and maintenance, while the 9/16" pedal spindle compatibility allows for versatile pedal options. Pedal washers are included for improved fitment. Please note, the bottom bracket is sold separately, and this crankset is not compatible with English 73mm bottom bracket shells, ensuring compatibility with most BMX frames.

Style & Use Case:

With its sleek black finish and minimalist design, the Promax HF-2 crankset is as stylish as it is functional. Perfect for BMX racing, dirt jumping, and street riding, it delivers superior stiffness and weight savings-key factors for competitive performance. Weighing only 28.9 oz (819 grams), it combines agility with durability for riders pushing the limits.

Innovative & Differentiating Features:

- Hollow-forged 6061-T6 aluminum crankarms for unmatched strength-to-weight ratio

- Steel spindle for enhanced durability and consistent performance

- 104mm BCD for versatile chainring upgrades (sold separately)
