Packed with technology, the Star Lite I-Proff is built around a carbon fibre reinforced and self-supporting twin shell. This highly advanced shell is designed to be impact proof and is a Nylon composite with 15% of the material being carbon fibre. This optimises power transfer, reduces pressure on the perineum and reduces the overall weight. Backing this up is the highly advanced tri-density padding, which offers varying density to provide the correct type of support in all riding positions.

These resist flexing during your most powerful sprints and ensure you’ll remain consistently comfortable as you push yourself to your limits.
