CNTs are used to manufacture golf balls adding advantages such as strength, durability, and abrasion resistance. CNTs and carbon fiber are also used in golf clubs to reduce the weight and the torque of the clubs while adding stability and control.

Track bicycles are now lightweighted with all carbon fiber frames and feature disc wheels created from a single piece of carbon fiber, reducing the weight of the bicycle and reducing wear and tear on the wheels. Some cyclists are even wearing carbon fiber shoes to protect their feet without adding weight.

Carbon fiber has even found its way into the pool, as swimwear company Arena uses carbon fiber in its high-tech racing suits to add flexibility, compression, and durability.
