New Super SLR Design relocates the brake lever pivot for better mechanical advantage. Synchronized with the new brake arch pivot a greater level of modulation and power are available from the tops of the brake hoods, where most people ride a majority of the time. Internal Cable routing gives lighter steering action and a cleaner handlebar area while fit can be customized through a series of shims creating reach adjustment. Two sizes of shims reduce reach by 5mm or 10mm for maximum comfort and control. Available in silver or black the new 105 levers are compatible with Ultegra 6700 and Dura-Ace 7900 brake arches.
