Ritchey's first full-carbon stem was designed to meet the needs of high-wattage European Classics specialists. 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 fiber, increased boom diameter and a wider clamp. Gram for gram this is the stiffest, most advanced Ritchey stem ever. C260 bar clamp creates a larger stem-to-bar interface, drastically reducing bolt stress 4 x T-20 faceplate bolts and patented 260 degree bar clamp design reduces weight, increases stiffness and distributes stress more evenly 3 x T-20 steer tube bolts and curved clamp slot reduces weight and steer tube stress Fits most road and mountain bars Material: Carbon with 2014 alloy faceplate Lengths: 80 - 130mm Angle: 84/6 degree Steerer Height: 42mm Faceplate width: 42mm Steerer: 1-1/8" or 1-1/4" (International only) Matte UD carbon fiber finish 125g (110mm)
