Tube - Unidirectional - Bicycle - Downtube - 1.875 x 1.995 Inch (+Length Options) - 24" BLOWOUT TUBING Not eligible for return or exchange.

Unlike metals which have similar properties in all directions (isotropic), the properties of composites are varying, dependent on the orientation of the fibers in each layer. This tube is constructed utilizing multi-directional "uni" plies. This makes for a true workhorse of a tube with no frills. This tube is great for bending and compression applications however if you suspect this tube will be subject to general abuse in terms of abrasion / rocks etc. we would recommend you seek a fabric wrapped tube instead.

Features & Benefits

Roll wrapped tubing is manufactured using multiple layers of prepreg carbon fiber (and if noted, other) materials. In general each layer is about 0.006 inches thick which means that a tube with a wall thickness of 0.060 inches will typically be composed of 9-10 individual layers of carbon fiber. The number of layers (plys) allows us to vary the orientation of the fibers throughout the thickness, creating a high performance, engineered product.

*Please note, the diagram below shows an outer "0/90" ply however the product you are currently viewing does NOT have this outer twill ply.

*This diagram illustrates a "generic" layup. The SKU being viewed may not have the layup schedule shown in this diagram. To view this SKU's particular layup please check out the "LAYUP ORIENTATION" tab.
