Revolutionizing Carbon Fibre: Giant’s Custom Weaving and Precision Engineering

From Thread to Tarmac

Giant creates carbon fiber bike frames differently. Most brands buy pre-made carbon cloth. This cloth consists of woven fibers coated with resin. They heat it in special ovens to solidify it into frames.

Giant chooses to buy raw threads from Japan and weaves the carbon itself. This method lets Giant customize the material’s weight, stiffness, and strength.

During a tour, we saw looms weaving carbon. These machines pull numerous threads from spools to create composite sheets. Giant’s woven carbon appeared in the TCR model, making it the lightest series of pieces in their carbon offerings.

More Accurate than Lasers

Giant improved its cutting process by moving away from lasers. While lasers cut accurately, they also introduce heat. This heat causes resin on the edges to activate and create uneven surfaces. Giant needed smooth edges for better strength in its frames.

The new method, ‘cold blade cutting’, eliminates these imperfections. This change reduced the number of pieces needed for a TCR Advanced SL frame from 380 to 270.

Hands-On Approach

Technicians hand-lay the cut pieces into molds. They undergo extensive training before working on premium frames. Each technician trains for more than six months.

The assembly area maintains a clean and controlled environment. Dust extraction and refrigeration ensure that materials remain clean and at the right temperature.

10,000km of Testing

After molding, Giant tests select frames for durability. They simulate 10,000km of use in their labs. This testing includes stress from pedaling and road impacts.

Each carbon fork goes through an X-ray check to ensure quality before moving to the assembly line.

Giant ensures that every frame meets high standards through rigorous testing and quality checks.
