shifting ever for a road bike. Functional, ultra cool-looking and practical, at only
88 grams per set for front and rear, these are the lightest, most precise cable

and tested Aztec PTFE DuracoteTM inner wires, this precision engineered system is
a breakthrough in control cable function, providing the most precise shifting
experience yet for any component group.
