Why we use more elastic spandex? Most Bike Shorts are made from a stretchy fabric. There are several reasons for using spandex in knitted fabrics one of which is the ability to move, the second is the ability to provide muscle support through compression. The fabrics used for road bike shorts are usually a six way, tricot, knit nylon or polyester. The lightweight fabrics are about 5.5 to 6 ounces per square yard. A medium weight is about 6.5 ounces and a heavy weight fabric would be about 8 ounces per square yard. The reason this fabric is used is primarily because of the freedom of movement and comfort during cycling. The higher the spandex content - the more compression on the muscles. High Spandex content is a sign of compression support for high end bike shorts. The higher the spandex, the more stretchy and supportive the fabric is. This compression massages the muscles to help work out lactic acid. The compression also helps to enhance blood flow to the muscles which helps reduce fatigue by keeping fresh blood circulating to the working muscles.

This is the latest update to our Balnna cycling shorts. This is a high end, long distance cycling short from the designers and engineers who work at Aero Tech Designs. Ideal for avid cyclists who need muscle support for intense cycling. The shorts have a light compression to compress muscles for a light massaging support. The fabric is a blend of stretch nylon and spandex yarns that help the moving muscles and reduce movement from vibrations. The fabric we use in our All Day cycling shorts was tested on our Martindale Abrasion Tester and it passes the test perfectly. The fabric is rugged and stretches in all directions yet is soft to the touch. Add Chamois Material:this lines the crotch area and adds a protective layer of padding between you and your seat that prevents excess friction and heat, eliminates chafing, absorbs vibrations from the road and trail.
