CST is the bicycle brand of Cheng Shin Rubber, also known as Cheng Shin Tyre, founded in 1967 in Taiwan. It grew to become one of the world’s largest manufacturers of bicycle tyres and tubes, backed by factories in Taiwan, China and beyond, and distribution in over 150 countries. The brand’s heritage means serious knowledge in rubber technology and tyre construction.

That legacy filters into every CST tube and tyre found at 99 Bikes. From puncture-resistant sidewalls to tubeless-ready casings, the same engineering that powers global fleets helps keep mainland riders rolling confidently on local roads and rugged tracks.
