Ritchey Superlogic Representing the bleeding edge of design and material technology, the SuperLogic moniker is reserved for an extremely select group of components. From a wheelset that is so slippery that decals will slow them down, to handlebars that defy conventional thought about what strength and light weight truly mean, our SuperLogic line is set to shake up the order of things literally. Ritcheys first full-carbon stem was designed to meet the needs of high-wattage European Classics specialists. Gram for gram this is the stiffest, most advanced Ritchey stem ever. The Carbon C260 adds to the amazing strength-to-weight ratio of our C260 alloy and Carbon Matrix stems through the use of high modulus carbon fibre, increased boom diameter and a wider clamp.
