Crankbrothers new premium XC Cobalt 11 stem made of unidirectional high modulus carbon with torx clamping bolts for 31,8 mm oversize handlebars. The Crankbrothers clamp system uses just two torx bolts. Because no faceplate is used the bar has to be slid through the clamp. Therefore the system is limited for bars with up to 15 mm rise. Besides the great functionality the Cobalt 11 stem looks very stylish.
