From th look website..{ The unique C-Stem was designed especially for the 695, taking advantage of the headset to feature a completely smooth finish around the back. Two small covers hide the clamp and adjustment mechanism. The latter enables you to change the angle from -9˚ to +13˚ and avoid using a stack of spacers which, aside from being unsightly, LOOK say decreases a bike’s front-end rigidity. The C-Stem also includes a ‘moon-shaped part’ that sits on one side of the bar and lets you change the reach by 10mm.}
