REAL-WORLD FAILURE GALLERY

While our rims are rated for 26~35 psi, real-world gravel racing often pushes pressures down to 15-23 psi for maximum traction. This low pressure, combined with thin flange designs, leads to catastrophic rim failures. See how our thick hook and high flange solve this.

How DK Solves This Failure

DK Reinforced Hook & Flange: Extra carbon thickness absorbs heavy rock strikes, preventing cracks and keeping your ride safe in low-PSI gravel racing.

Market Standard Thin Flange Rims

DK Reinforced Thick Flange Rims

❌ Vulnerable Thin Flange

Standard thin rim walls fail under direct ground impacts.

✅ Thick Hook & Elevated Flange

Reinforced carbon structure resists severe rock strikes.

❌ High Delamination Risk

Low tire pressure (15–23 PSI) causes carbon layers to split.

✅ High Impact Resistance

Absorbs high-energy bottom-outs without cracking.

❌ Unreliable for Racing

Sudden rim failure forces you to abandon your ride.

✅ Built for Extreme Gravel

Provides maximum traction and confidence on harsh terrain.

Don't let a 15 PSI rock strike end your ride.

DK's Reinforced Thick Hook & Elevated Flange protects your ride.

Product Development Process

1 Layup / Pre-molding Process

Precision Ply Cutting & Layering

Using high-grade Toray T700, T800, and T1000 carbon prepregs, material is precisely cut and stacked according to strict engineering blueprints. Every single ply is customized with exact dimensions, multi-angle schedules (0°, 45°, 90°), and controlled layer counts to lay a high-performance foundation.

Optimized Material Staging & Roll Management

In the dedicated material staging zone, high-quality carbon fiber prepreg rolls—ranging from 15–20mm to 20–25mm widths—are systematically organized. Under strict tension and temperature control, the material is prepared for continuous, defect-free feeding into the production line.

Skilled Manual Roll Forming

Highly experienced technicians execute meticulous manual roll forming and lamination. Incorporating hundreds of distinct, multi-angle carbon strips, this hands-on craftsmanship ensures optimal compaction, eliminating air gaps and maximizing structural strength and impact resistance.

2 Molding Process

High-Precision Mold Preparation & Alignment

Pre-molded rim blanks are carefully aligned in high-strength alloy molds. Strict temperature and pressure monitoring ensures flawless compaction and seamless carbon layer bonding during curing.

Thermal Curing & De-molding Quality Control

Rims undergo controlled hot-press curing under extreme pressure to eliminate air voids. Once de-molded, each rim is rigorously inspected for structural integrity and surface smoothness.
