Silca Nastro Piloti is a 1.85mm-thick tape for aggressive riding and racing which provides cushioning equivalent to 2.5mm thick tapes of existing technology. The Asymmetric Piloti Texture inspired by F1 tire technology allows the tape to be wrapped in either a moderate-texture or high-texture format depending on preference. Inspired by advancements in running shoe foam and F1 tires as well as our own research into rolling efficiency, impedance, and damping, we realized that materials technology could allow for a significant improvement in bar tape. Using a laminate of SILCAthane, SILCAlon and 3M Visco-elastic adhesive instead of a single-foam extrusion, the tape can be optimized across a range of desired features. The resulting tape has a softer, more comfortable feel, higher wet and dry grip, better vibration isolation, and 3-5x the durability of existing tape materials. Since the actual wrap of the tape can be as important as the tape itself, we've also developed a full adhesive backed 'butterfly' to better cover the back of the lever clamp area without adding bulk, a high-grip finishing tape, and expanding aluminum/composite end plugs to ensure every detail is perfect. - Ultra Performance 1.85mm thick Tri-Laminate design delivers equivalent cushioning to 2.5mm tapes - Racecar inspired Dual-Tread deboss allows the tape to be wrapped for High Grip or Max Grip depending on wrap direction - Aluminum expanding bar-end plug - PU finishing tape - Butterfly shaped brake clamp cover
